Abstract

An OpenFOAM based solver for dilute laminar gas-droplet ows with evaporation is developed. The same module was implemented in a general purpose CFD solver, IITK-DAE ANUPRAVAHA SOLVER by Mrunalini [4] and Shashwat Swami Jaiswal [38]. A proposal for turbulent module for the same also has been made in this thesis. The nite volume method with non-staggered grid arrangement has been used along with a fully implicit and semi-coupled algorithm to numerically solve the set of governing equations for laminar case. A two-way coupling has been assumed between the two phases. This has been achieved by including source terms in the governing equations, involving mass, momentum and energy transport between the phases. A classical model for droplet evaporation has been implemented in the OpenFOAM based solver. The solver has been successfully veried against the results of gas-droplet channel ow with evaporation against the results of Anupravaha and compared with that of the commercial software FLUENT. A proposal for a two equation (k-) turbulent model for gas-droplet ows with evaporation has been made in this thesis. Taking the density variation in gaseous phase due to mixing into account, Favre-averaging is considered for this phase.
