Abstract

This paper demonstrates the capabilities of the Boundary Element Method (BEM) and the Boundary/Domain Integral Method (BDIM) in determining boundary conditions in multi- domain problems involving heat conduction and linear heat conduction/convection. The effect of the conductivity ratios between multiple regions is examined and it was found that the condition number of the solution matrix increases with an increasing conductivity ratio. The BDIM was also used to solve the thermal energy equation in a fluid given a known velocity and pressure field. An iterative boundary condition correction procedure for exit thermal boundary conditions in computational fluid dynamics analysis is discussed. A conjugate conduction/convection heat transfer problem was also
