Numerical Modeling of Wet Steam Flow in Steam Turbine Channel
In power station practice, work is extracted from expanding steam in three stages namely High Pressure(HP), Intermediate Pressure(IP) and Low Pressure(LP) turbines. During the expansion process in the LP turbine, the steam cools down and at some stages, it nucleates to become a two-phase mixture. It is well-acknowledged in the literature that the nucleating and wet stages in steam turbines are ...
متن کاملAdiabatic Product Expansion
The time-evolution operator for an explicitly time-dependent Hamiltonian is expressed as the product of a sequence of unitary operators. These are obtained by successive time-dependent unitary transformations of the Hilbert space followed by the adiabatic approximation at each step. The resulting adiabatic product expansion yields a generalization of the quantum adiabatic approximation. Further...
متن کاملApproximating the Adiabatic Expansion of a Gas
We begin by allowing a gas to occupy a well insulated vessel, where the pressure (Pinitial) is a bit higher than atmospheric pressure (Vinitial and Tinitial are known). The vessel is then opened and closed rapidly, allowing the gas to escape at an intermediate pressure equal to atmospheric pressure (Pinter). The speed with which this is done is crucial, because if there is appreciable heat loss...
متن کاملinvestigation of the effects of coalescence on the wet steam flows
condensing flows in nozzles and fixed blades of steam turbine have always been the subject of many studies.in such flows, existence of liquid phase in vapor changes the nature of the flow. the major of changes are due to four main mechanisms included nucleation, droplet growth, coalescence and breakage of droplets. in this paper,the effects of coalescence process between droplets have been inve...
متن کاملBreakup of three particles within the adiabatic expansion method
General expressions for the breakup cross sections in the laboratory frame for 1 + 2 reactions are given in terms of the hyperspherical adiabatic basis. The three-body wave function is expanded in this basis and the corresponding hyperradial functions are obtained by solving a set of second order differential equations. The S matrix is computed by using two recently derived integral relations. ...
