aIn this model, it is assumed that during the vaporization process, only a fraction y of the fluid is transformed into saturated mixture, the other fraction (1-y) remains metastable liquid and is submitted to an isentropic evolution. 在这个模型,它假设,在汽化过程期间,只有流体的分数y被变换成饱...
Assume this process to be followed by an isentropic compression stroke [a2] , the pressure in the cylinder after compression can be easily pr 为二冲程柴油引擎,空气在引擎的圆筒首先被咽下然后被压缩。 在入口空气是压缩的之后,压力在圆筒非常高。 假设一个等熵的压缩冲程将跟随的这个过程(a2),压力在...

A heat engine for carrying out the process comprises; an isothermal compressor to which a liquid injection mechanism is connected; an isentropic compressor; an expansion machine to which a vapor generator is connected; and at least one additional expansion machine with liquid separator; said ...
The isentropic efficiency of a turbine is given as 0.74, and the actual work was measured as 111 kW for the 0.9 kg/s mass flow rate of steam. What is the specific isentropic turbine work (kJ/kg)? (a) What is the hot reservoir temperature of a Carnot engine that has an efficiency of...
Statistical analysis in terms of microstate probabilities p_{i}(t) uniquely identifies dW(t) as isentropic and dQ(t) as isometric (see text) change in dE(t); such a clear separation does not occur for exchange quantities. Hence, our new formulation of the first law provides tremendous ...
In some cases, a viscous fluid pump may be better suited to achieve the required flow rate. Gas characteristics: Gases also require a thorough understanding of their characteristics. For example, the requirements placed on the membrane pump can vary depending on the gas type, its isentropic ...
Why is a reversible adiabatic process isentropic? How does pressure affect kinetic energy? Why is methane such a potent greenhouse gas? Why is air combusted in a rocket engine? Why is nitrogen classified as a greenhouse gas? Why are trace gases important? Why can't cold air hold much water...
DifferentiatingWtwith respect topiand equatingdWt/dpito zero the value ofpithat would yield the maximum turbine work output with isentropic expansion is given by (7.38)pi=p6p7 and (7.39)p6pi=pip7=rpi=p6p7=rp In the T-S diagram (Figure 7.16) the increase in cycle work is shown by the ...
2) Isentropic compression 等熵压缩 1. The hydrodynamic process of the gas capsule compression with a single radiative pulse drive is divided into four phases: shock compression,nearly isentropic compression,compression and expansion with temperature reduction. 单脉冲辐射驱动冲击波压缩气体靶动力学过程...
