Abstract

Analytical study of forced convection phenomenon with turbulent flow is complex. The aim of the project is to enhance heat transfer by optimizing the design of domain. In this study forced airflow for heat input will be carried. Naturally convection depends on fluid parameters and geometry of the domain through which fluid flows. The aim of our project is to find the value of heat transfer coefficient ‘h’ for turbulent flow in heat transfer systems. In convection important parameter is, heat transfer coefficient ‘h’ because, it determines rate of heat transfer. A study of literature on heat transfer coefficients shown very little work carried out for different non circular duct. This project uses analysis of flow both for circular and non-circular duct based experimental results to determine heat transfer coefficient, and comparison of heat transfer coefficient for circular, ellipse, and triangular duct will be carried out. For the enhancement of heat transfer of circular, ellipse, and triangular duct passive method is used, and the duct which gives maximum heat transfer coefficient is be optimized. For modelling and meshing ICEM-CFD has been used. For analysis CFX has been use and for results CFD-POST has been used.
