چکیده
The aim of the present study is to analyse the natural convection through numerical simulation in a trapezoidal shaped enclosure intact with a uniformly heated cylinder. The purpose of this study is to investigate the effect of various controlled parameter like trapezoidal angle (95°- 115°), cylinder position (CP1- CP5), Rayleigh number (1 × 105- 1 × 107) and for different boundary conditions of the enclosure walls on the rate of heat transportation. A control volume approach with SIMPLE algorithm is used to solve the governing conservation equations for laminar, steady, two-dimensional natural convection. It has been observed during analysis that the flow movement of the fluid has been affected substantially when the cylinder position changes to different locations which leads to the variation in the rate of heat transfer. Furthermore, the rise in heat transfer is observed when the enclosure angles and Rayleigh number are changed in ascending order. This study covers the impact of trapezoidal angle along with heated cylinder position on the heat transportation.
