TLDR
In this paper, a control-volume-based finite difference procedure with appropriate averaging for the diffusion coefficients is used to solve the coupling between the solid and fluid regions, and the analysis is extended to study the optimum spacing between heat sources for a fixed heat input and a desired maximum temperature at the heat source.Abstract:
Conjugate heat transfer for two-dimensional, developing flow over an array of rectangular blocks, representing finite heat sources on parallel plates, is considered. Incompressible flow over multiple blocks is modeled using the fully elliptic form of the Navier-Stokes equations. A control-volume-based finite difference procedure with appropriate averaging for the diffusion coefficients is used to solve the coupling between the solid and fluid regions. The heat transfer characteristics resulting from recirculating zones around the blocks are presented. The analysis is extended to study the optimum spacing between heat sources for a fixed heat input and a desired maximum temperature at the heat source.read more

Convective flow and heat transfer in a channel containing multiple heated obstacles
Timothy J. Young,Kambiz Vafai +1 more
TL;DR: In this paper, a numerical simulation of forced convective, incompressible flow in a channel with an array of heated obstacles attached to one wall is presented, and three levels of Nusselt numbers are emphasized in this systematic analysis: local distributions along the obstacle exposed faces, mean values for individual faces, and overall obstacle mean values.
