Thermophysical Properties of Dense Molten %${\text{Al}}_{2}{\text{O}}_{3}%$ Determined by Aerodynamic Levitation
Abstract Aerodynamic levitation (ADL) is a widely used contactless technique for evaluating the thermophysical properties of molten materials. During data analysis, these molten samples are typically assumed to be bubble-free and to adopt an oblate spheroid shape. However, these assumptions have not...

| 520 | |a Abstract Aerodynamic levitation (ADL) is a widely used contactless technique for evaluating the thermophysical properties of molten materials. During data analysis, these molten samples are typically assumed to be bubble-free and to adopt an oblate spheroid shape. However, these assumptions have not been empirically validated. The presence of trapped bubbles and potential deformation at the bottom of the levitated sample, which is obscured from view by the levitation nozzle, can lead to an underestimation of the sample’s density. These factors could also interfere with the sample’s damped oscillation, thereby affecting the reliability of the measured surface tension and viscosity. Consequently, in this study, we address these issues by using smaller alumina samples to minimize sample deformation and by inspecting each sample’s cross-section after cooling for trapped bubbles. This approach enabled us to mitigate the impact of these potential distortions on the measured thermophysical properties of molten alumina. Our findings reveal that the density of dense molten alumina can be expressed as 2.917%$-%$1.228%$\times 10^{-4}%$(T-2327) [g %$\cdot \hbox {cm}^{-3}%$] from 1978 K to 2789 K. Additionally, between 2375 K and 2770 K, we determined the surface tension of alumina to be 0.632%$-%$2.310%$\times 10^{-5}%$(T-2327)[N %$\cdot \hbox {m}^{-1}%$] and the viscosity to be %$0.577e^{9.743 \times 10^{3}/\hbox {T}}%$[m %$\cdot%$ Pa %$\cdot%$ s]. | ||

Abstract Aerodynamic levitation (ADL) is a widely used contactless technique for evaluating the thermophysical properties of molten materials. During data analysis, these molten samples are typically assumed to be bubble-free and to adopt an oblate spheroid shape. However, these assumptions have not been empirically validated. The presence of trapped bubbles and potential deformation at the bottom of the levitated sample, which is obscured from view by the levitation nozzle, can lead to an underestimation of the sample’s density. These factors could also interfere with the sample’s damped oscillation, thereby affecting the reliability of the measured surface tension and viscosity. Consequently, in this study, we address these issues by using smaller alumina samples to minimize sample deformation and by inspecting each sample’s cross-section after cooling for trapped bubbles. This approach enabled us to mitigate the impact of these potential distortions on the measured thermophysical properties of molten alumina. Our findings reveal that the density of dense molten alumina can be expressed as 2.917%$-%$1.228%$\times 10^{-4}%$(T-2327) [g %$\cdot \hbox {cm}^{-3}%$] from 1978 K to 2789 K. Additionally, between 2375 K and 2770 K, we determined the surface tension of alumina to be 0.632%$-%$2.310%$\times 10^{-5}%$(T-2327)[N %$\cdot \hbox {m}^{-1}%$] and the viscosity to be %$0.577e^{9.743 \times 10^{3}/\hbox {T}}%$[m %$\cdot%$ Pa %$\cdot%$ s].

During data analysis, these molten samples are typically assumed to be bubble-free and to adopt an oblate spheroid shape. However, these assumptions have not been empirically validated. The presence of trapped bubbles and potential deformation at the bottom of the levitated sample, which is obscured from view by the levitation nozzle, can lead to an underestimation of the sample’s density. These factors could also interfere with the sample’s damped oscillation, thereby affecting the reliability of the measured surface tension and viscosity. Consequently, in this study, we address these issues by using smaller alumina samples to minimize sample deformation and by inspecting each sample’s cross-section after cooling for trapped bubbles. This approach enabled us to mitigate the impact of these potential distortions on the measured thermophysical properties of molten alumina. Our findings reveal that the density of dense molten alumina can be expressed as 2.917%$-%$1.228%$\times 10^{-4}%$(T-2327) [g %$\cdot \hbox {cm}^{-3}%$] from 1978 K to 2789 K. Additionally, between 2375 K and 2770 K, we determined the surface tension of alumina to be 0.632%$-%$2.310%$\times 10^{-5}%$(T-2327)[N %$\cdot \hbox {m}^{-1}%$] and the viscosity to be %$0.577e^{9.743 \times 10^{3}/\hbox {T}}%$[m %$\cdot%$ Pa %$\cdot%$ s].</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Aerodynamic levitation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bubbles</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Density</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Molten alumina</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Surface tension</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Viscosity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Takatani, Tomoya</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Muta, Hiroaki</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fujieda, Shun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kondo, Toshiki</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kikuchi, Shin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kargl, Florian</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ohishi, Yuji</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">International journal of thermophysics</subfield><subfield code="d">New York, NY : Springer Science + Business Media B.V., 1980</subfield><subfield code="g">45(2023), 1 vom: 20.

Thermophysical Properties of Dense Molten %${\text{Al}}_{2}{\text{O}}_{3}%$ Determined by Aerodynamic Levitation |
| abstract |
Abstract Aerodynamic levitation (ADL) is a widely used contactless technique for evaluating the thermophysical properties of molten materials. During data analysis, these molten samples are typically assumed to be bubble-free and to adopt an oblate spheroid shape. However, these assumptions have not been empirically validated. The presence of trapped bubbles and potential deformation at the bottom of the levitated sample, which is obscured from view by the levitation nozzle, can lead to an underestimation of the sample’s density. These factors could also interfere with the sample’s damped oscillation, thereby affecting the reliability of the measured surface tension and viscosity. Consequently, in this study, we address these issues by using smaller alumina samples to minimize sample deformation and by inspecting each sample’s cross-section after cooling for trapped bubbles. This approach enabled us to mitigate the impact of these potential distortions on the measured thermophysical properties of molten alumina. Our findings reveal that the density of dense molten alumina can be expressed as 2.917%$-%$1.228%$\times 10^{-4}%$(T-2327) [g %$\cdot \hbox {cm}^{-3}%$] from 1978 K to 2789 K. Additionally, between 2375 K and 2770 K, we determined the surface tension of alumina to be 0.632%$-%$2.310%$\times 10^{-5}%$(T-2327)[N %$\cdot \hbox {m}^{-1}%$] and the viscosity to be %$0.577e^{9.743 \times 10^{3}/\hbox {T}}%$[m %$\cdot%$ Pa %$\cdot%$ s]. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2023.
