Abstract
The immersed boundary method (IBM) that has been populously used to represent non-slip conditions of velocity on complex and moving boundaries using rectangular coordinates has been extended to flow quantities other than the velocity with hon-homogeneous boundary conditions including Neumman-type conditions. The method is applied to compute velocity, thermal and scalar fields in non-isothermal flows. The method has been tested in the calculation of buoyant wall jets impinging on isothermal or adiabatic bodies. The calculation is first conducted in the case where the boundary position coincides with the computational grid points. The results are good and the method is found to be applicable to various practical problems.
