摘要

The entropy generation caused by heat conduction has been analyzed for physical situations related to cryostats. The situations under consideration are characterized by heat conduction with presence or absence of heat generation and/or heat convection. The existing information regarding the thermodynamic optimal design is compared with more realistic nonoptimal situations. The difference between the optimal and nonoptimal entropy generation has been analyzed from the quantitative point of view. It has been shown that the nonoptimal temperature distribution through a cryostat component might be a realistic option from the thermal design point of view. 13 refs., 5 figs., 1 tab.
