Conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. In the recovery system, super-critical an CO2 is employed as the working fluid operating in a Brayton cycle. Low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes th...
In this paper, the performance of arefrigeration cycle with double stage ejector is studied. Also the effect of some working fluids, the ejector geometry including the diameter change in the part of constant diameter at the first and second stages and operating parameters on the entrainment ratio of the first and second stages in the ejector and coefficient of performance cycle (COP) are studied....
Environmental and economic objective functions are used simultaneously to select the operating conditions of a steam and power plant. Different methodologies to solve bi objective optimization problems were implemented successfully. The life cycle potential environmental impact and the operating cost of the utility plant are minimized simultaneously. A methodology is presented to estimate the p...
This paper describes the fast-scale bifurcation phenomena of a single-stage single-switch power-factorcorrection (PFC) regulator comprising a boost stage operating in discontinuous conduction mode (DCM) and a forward stage operating in continuous conduction mode (CCM). The two stages combine into a single stage by sharing one main switch and one control loop. Using ‘exact’ cycle-by-cycle comput...
