In order to better understand the flow physics and boiling phenomenon, numerical simulation of the flow patterns developed in the flow boiling has been carried out and validated with the published experimental results. Simulations were carried out for R-134a as a working fluid with 1.75 mm circular channel and heated length of 600 mm. VOF method has been used to capture the liquid-vapour interface. Numerical simulations were in good agreement with the experimental results of flow patterns for lower values of heat and mass fluxes. But some discrepancies were observed at medium and higher values of heat and mass fluxes.
