Structural Design and Parameter Analysis of Ship Inlet Distortion Simulation Boards

Abstract Significant aerodynamic engine instability can occur during the operation of marine gas turbines as airflow enters the compressor through a 90° turning and causes inlet distortion. This study adopts the method of simulating board equivalence to provide the target distortion flow field for s...

520			\|a Abstract Significant aerodynamic engine instability can occur during the operation of marine gas turbines as airflow enters the compressor through a 90° turning and causes inlet distortion. This study adopts the method of simulating board equivalence to provide the target distortion flow field for ship compressors. The characteristics of the flow field behind the simulated board are obtained through experiments and numerical simulations, through which the relationship between the height of the simulated board and the total pressure distortion is elucidated. Subsequently, the study summarizes the prediction formula to achieve a distortion prediction of 0.8%–7.8%. In addition, this work analyzes the effects of drilling methods and diameters on flow nonuniformity by drilling holes into the simulation board. The results indicate that drilling holes on the board can weaken the nonuniformity of the flow field within a certain range and change the distribution pattern of total pressure in the cross-section. Furthermore, the total pressure distortion no longer changes significantly when the number of holes is too large. The proposed double simulation board structure is capable of obtaining the following two types of distorted flow fields: symmetrical dual low-pressure zones and low-pressure zones with high distortion intensity at the compressor inlet. The distortion equivalent simulation method proposed in this work can obtain various types of distortion spectra, thereby meeting the distortion parameter requirements for the antidistortion testing of marine engines.

This study adopts the method of simulating board equivalence to provide the target distortion flow field for ship compressors. The characteristics of the flow field behind the simulated board are obtained through experiments and numerical simulations, through which the relationship between the height of the simulated board and the total pressure distortion is elucidated. Subsequently, the study summarizes the prediction formula to achieve a distortion prediction of 0.8%–7.8%. In addition, this work analyzes the effects of drilling methods and diameters on flow nonuniformity by drilling holes into the simulation board. The results indicate that drilling holes on the board can weaken the nonuniformity of the flow field within a certain range and change the distribution pattern of total pressure in the cross-section. Furthermore, the total pressure distortion no longer changes significantly when the number of holes is too large. The proposed double simulation board structure is capable of obtaining the following two types of distorted flow fields: symmetrical dual low-pressure zones and low-pressure zones with high distortion intensity at the compressor inlet.

This study adopts the method of simulating board equivalence to provide the target distortion flow field for ship compressors. The characteristics of the flow field behind the simulated board are obtained through experiments and numerical simulations, through which the relationship between the height of the simulated board and the total pressure distortion is elucidated. Subsequently, the study summarizes the prediction formula to achieve a distortion prediction of 0.8%–7.8%. In addition, this work analyzes the effects of drilling methods and diameters on flow nonuniformity by drilling holes into the simulation board. The results indicate that drilling holes on the board can weaken the nonuniformity of the flow field within a certain range and change the distribution pattern of total pressure in the cross-section. Furthermore, the total pressure distortion no longer changes significantly when the number of holes is too large. The proposed double simulation board structure is capable of obtaining the following two types of distorted flow fields: symmetrical dual low-pressure zones and low-pressure zones with high distortion intensity at the compressor inlet. The distortion equivalent simulation method proposed in this work can obtain various types of distortion spectra, thereby meeting the distortion parameter requirements for the antidistortion testing of marine engines.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Total pressure distortion</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ship compressor inlet</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Simulation board</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Distortion simulation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Experimental study</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">He, Chenxin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Qu, Yonglei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of marine science and application</subfield><subfield code="d">Springer Berlin Heidelberg, 2002</subfield><subfield code="g">23(2024), 1 vom: 26.

abstract	Abstract Significant aerodynamic engine instability can occur during the operation of marine gas turbines as airflow enters the compressor through a 90° turning and causes inlet distortion. This study adopts the method of simulating board equivalence to provide the target distortion flow field for ship compressors. The characteristics of the flow field behind the simulated board are obtained through experiments and numerical simulations, through which the relationship between the height of the simulated board and the total pressure distortion is elucidated. Subsequently, the study summarizes the prediction formula to achieve a distortion prediction of 0.8%–7.8%. In addition, this work analyzes the effects of drilling methods and diameters on flow nonuniformity by drilling holes into the simulation board. The results indicate that drilling holes on the board can weaken the nonuniformity of the flow field within a certain range and change the distribution pattern of total pressure in the cross-section. Furthermore, the total pressure distortion no longer changes significantly when the number of holes is too large. The proposed double simulation board structure is capable of obtaining the following two types of distorted flow fields: symmetrical dual low-pressure zones and low-pressure zones with high distortion intensity at the compressor inlet. The distortion equivalent simulation method proposed in this work can obtain various types of distortion spectra, thereby meeting the distortion parameter requirements for the antidistortion testing of marine engines. © Harbin Engineering University and Springer-Verlag GmbH Germany, part of Springer Nature 2024
