Experimental Studies of Processes in a Cylinder with Cryogenic Filling Based on a Power Plant

Presently, cryogenic engineering is a rapidly advancing area of the global economy. One requirement is to use some of the energy that has already been used to convert methane, oxygen, hydrogen, nitrogen, helium, and other gases into liquid state. This can be achieved, for instance, in power plants that operate on the Rankine cycle. In such plants, the increase in pressure of the working fluid can be achieved either by using a pump or by employing thermal compression, which is a more efficient method. A noteworthy device that utilises the process of thermocompression in a constant volume is a cylinder with cryogenic filling (CCF). This device is capable of meeting the requirements of current technologies for utilising compressed gases and cryogenic liquids. Consequently, the study yielded results about the cylinder filled with cryogenic substance in a flow mode, under different inlet pressures to the engine-generator. Additionally, the experiment successfully controlled the errors associated with the measured values.
