Özet
Purpose: The purpose of this study is to compare experimentally and numerically the in-cavity velocity and temperature distributions obtained for different rotation speeds and different rotation directions of the fan used in a domestic oven with a fan and to determine the parameter values that will provide homogeneous and fast cooking at the end of the study.Theory and Methods: In this study, the motor rotation speed in the cavity was examined from 600 rpm to 2400 rpm. At the same time, velocity data were taken experimentally with a hot wire probe from local points on three planes determined in the cavity. In addition, experimental temperature data were taken with thermocouples. In parallel with the study, Ansys Fluent program was used in the numerical solution phase.Results: As a result of the study, experimental and numerical results were found to be compatible with each other. Among the turbulence models examined, the kw SST model was found to be the most stable and accurate model. When the outputs of the numerical thermal studies were compared with the experimental data, the highest deviation of 3% was found.Conclusion: It was observed that as the rotational speed of the fan-motor group increased, the average velocity and standard deviation values on the planes in the cavity also increased. For homogeneous cooking, it was determined that the standard deviation value on the planes was the minimum and the average temperature on the planes was the closest to the targeted temperature with a motor rotation speed of~ 2272 rpm and clockwise motor rotation direction.
