![]() It has been assumed that the overall convective heat transfer coefficient is composed from the nucleate boiling convective coefficient and the forced turbulent convective coefficient. The thermal heat transfer to evaporating two-phase crude oil mixture occur by bubble generation at the wall (nucleate boiling) has been calculated by using Chen correlation. The thermo-physical properties (such as: thermal conductivity, heat capacity, surface tension, viscosity) of the crude oil were estimated by using empirical correlations. FDS code is formulated based on CFD (Computational Fluid Dynamics) of fire heater. The computational model is composed of two phases-Simulation of fire by using Fire Dynamics Simulator software (FDS) version 5.0 and then a nucleate boiling computation of the crude oil. ![]() The heat flux produced from burner is transferred to the crude oil flowing inside the tube. The proposed model is composed from Heptane fire heater and a tube array. ![]() ![]() An advanced algorithm has been developed in order to analyze the performance of re-boiling process of crude oil flowing inside reboilers tubes. ![]()
