Numerical investigation of triangular bluff bodies size effect on heat and mass transfer phenomena: internal flow
Abstract A numerical simulation procedure has been exerted based on the finite element method to investigate the triangular cylinder geometrical configuration effect on the flow pattern, heat and mass transfer phenomena inside a two-dimensional channel for the range 320 ≤ Re ≤ 1000. For this purpose...

| 520 | |a Abstract A numerical simulation procedure has been exerted based on the finite element method to investigate the triangular cylinder geometrical configuration effect on the flow pattern, heat and mass transfer phenomena inside a two-dimensional channel for the range 320 ≤ Re ≤ 1000. For this purpose, seven different types of triangular cylinders have been proposed, and drag coefficient, Nusselt number, Strouhal number, mixing quality, vorticity and temperature distributions have been presented for all types for a Prandtl number value of 0.71. Moreover, the thermal and mixing performance indices have been presented according to the value of pressure drop for obtaining the best type of triangular cylinder. Detailed results revealed heat and mass transfer enhancement for types 1 to 5 (that the triangle’s height increases) due to the high level of vortex shedding compared to the types 6 and 7 (that the triangle’s base size decreases). Type 5 illustrates the maximum performance than the others according to stronger vortices shedding from the bluff body and thinner boundary layer formation on the channel walls. On the other hand, by considering the pressure drop, type 5 gives the maximum thermal performance index than other cases. Finally, type 6 enhances the mass performance index more than the other types while it has less pressure drop. | ||

For this purpose, seven different types of triangular cylinders have been proposed, and drag coefficient, Nusselt number, Strouhal number, mixing quality, vorticity and temperature distributions have been presented for all types for a Prandtl number value of 0.71. Moreover, the thermal and mixing performance indices have been presented according to the value of pressure drop for obtaining the best type of triangular cylinder. Detailed results revealed heat and mass transfer enhancement for types 1 to 5 (that the triangle’s height increases) due to the high level of vortex shedding compared to the types 6 and 7 (that the triangle’s base size decreases). Type 5 illustrates the maximum performance than the others according to stronger vortices shedding from the bluff body and thinner boundary layer formation on the channel walls. On the other hand, by considering the pressure drop, type 5 gives the maximum thermal performance index than other cases.

For this purpose, seven different types of triangular cylinders have been proposed, and drag coefficient, Nusselt number, Strouhal number, mixing quality, vorticity and temperature distributions have been presented for all types for a Prandtl number value of 0.71. Moreover, the thermal and mixing performance indices have been presented according to the value of pressure drop for obtaining the best type of triangular cylinder. Detailed results revealed heat and mass transfer enhancement for types 1 to 5 (that the triangle’s height increases) due to the high level of vortex shedding compared to the types 6 and 7 (that the triangle’s base size decreases). Type 5 illustrates the maximum performance than the others according to stronger vortices shedding from the bluff body and thinner boundary layer formation on the channel walls. On the other hand, by considering the pressure drop, type 5 gives the maximum thermal performance index than other cases. Finally, type 6 enhances the mass performance index more than the other types while it has less pressure drop.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield

Numerical investigation of triangular bluff bodies size effect on heat and mass transfer phenomena: internal flow |
| abstract |
Abstract A numerical simulation procedure has been exerted based on the finite element method to investigate the triangular cylinder geometrical configuration effect on the flow pattern, heat and mass transfer phenomena inside a two-dimensional channel for the range 320 ≤ Re ≤ 1000. For this purpose, seven different types of triangular cylinders have been proposed, and drag coefficient, Nusselt number, Strouhal number, mixing quality, vorticity and temperature distributions have been presented for all types for a Prandtl number value of 0.71. Moreover, the thermal and mixing performance indices have been presented according to the value of pressure drop for obtaining the best type of triangular cylinder. Detailed results revealed heat and mass transfer enhancement for types 1 to 5 (that the triangle’s height increases) due to the high level of vortex shedding compared to the types 6 and 7 (that the triangle’s base size decreases). Type 5 illustrates the maximum performance than the others according to stronger vortices shedding from the bluff body and thinner boundary layer formation on the channel walls. On the other hand, by considering the pressure drop, type 5 gives the maximum thermal performance index than other cases. Finally, type 6 enhances the mass performance index more than the other types while it has less pressure drop. © The Author(s), under exclusive licence to The Brazilian Society of Mechanical Sciences and Engineering 2022 |
