چکیده مقاله :
Present paper is a result of consideration in reducing steady-state time of heating systems. For this purpose one should study boundary condition of the system until steady state condition. In the research, a laboratory heating system was considered using numerical simulation and the numerical results were compared with several experimental tests. Studies shows that the steady-state time reduces significantly via two major methods called "Initial Heat Method" and "Initial Velocity Method". These two methods can apply in experimental tests planning and also in numerical simulation programs. Complete results for the experiments of both methods were presented in previous papers, and a little survey of them with some physical analysis from similar heating systems was explained in this research. Furthermore two correlation equations were presented for dimensionless time vs. dimensionless initial heat and dimensionless initial velocity using statistical methods.
