Abstract:
Prospects of nanotechnologies used for designing more effective thermomechanical devices and systems based on repulsive clathrates are outlined. Basic differences in thermodynamic properties of repulsive clathrates (that can be used for dissipation, accumulation, and transformation of large amount of energy in small volumes of working chambers) and traditional working bodies (gas/vapor) are demonstrated. Among unexpected characteristics of the systems being developed, the dependence of the adiabatic exponent on the parameters of the system is detected and negative values of the thermal elasticity coefficient are confirmed. The possibility of improving the accuracy of diagnostics of capillary-porous materials by taking into account additionally the thermal effects observed in repulsive clathrates is demonstrated.
