碩士 / 國立高雄應用科技大學 / 機械與精密工程研究所 / 99 / This article uses the Fluent simulation software package to analyze the control of mixed convection in a lid-driven square cavity by using a conductive fin and a heat source (forced and natural convection combined). This study simulates both the flow field and temperature field numerically. The square cavity is constructed with two vertical walls having differential temperature and two adiabatic horizontal walls. The upper lid could be moving continuously in the right or left-direction respectively, while in the center of the bottom wall is embedded with a heat source. A rectangular conductive fin is located on either vertical wall. In the study, there are six different locations for the rectangular conductive fin to be discussed. Numerical simulations show that the conductive fin is a good control way in keeping temperature distribution and heat transfer rate in the flow field, which also predicts enhancing the efficiency of heat transfer in the cavity. The governing physical parameters employed in this study include Grashof number (Gr = 10^5、10^6 and 10^7 ), heating intensity parameter (R = 100、500、1000), the lid moving direction, i.e., to the left（-X） or to the right（+X）,and other parameters. The simulation results are discussed and displayed with the flow field and temperature field.
