Evaluating the particle location in particle-laden flows is the most important parameter for calculating the two-phase flow parameters and also controls the computational time. In heat conducting nanofluids the volume fraction of particles is typically less than 3%. Nevertheless the their effect on heat transfer is important. In this paper, a new method for coupling thermal effects of dispersed and continuum phases is introduces. The L-N-R search algorithm, which can be used in complex geometries and unstructured grid is used for specifying particle location. For low volume fractions, particles-fluid interaction is considered only for the energy exchange. This exchange is done using a binary search tree. It is shown general usage of nanofluids in microchannels should be done by special considerations.
