Computational Study of Radiative and Convective Heat Transfer in a Cylindrical Combustion Chamber |
|
| چکیده انگلیسی مقاله |
In this paper, the effect of cold air on the fluid flow inside the cylindrical combustion chamber and its wall temperature distribution have been studied computationally, taking into account the effect of radiative heat transfer from hot gases. The results have been compared with the case that radiative heat transfer was neglected. It is observed that the reattachment length increases when increasing the expansion ratio, and mixing of two fluid flows are not affected by temperature. As mixing is directly related to turbulence, higher turbulence will cause uniform mixture in a shorter length and sudden expansion is helpful for faster mixing. The results show that the combustion chamber wall temperature due to gas radiation will increase very quickly at the entrance and will then decrease rapidly, while neglecting the radiation effect, the wall temperature will increase monotonically. |
