Energy storage shock wave

How much entropy is produced in a shock wave?

The entropy production in the weak and strong shocks were approximately proportional to the square of the Mach number and decayed with time at approximately the same relative rate. In both cases, some 97% of the total entropy production in the gas occurred in the shock wave.

How does shock compression affect energy storage and heat dissipation?

Energy storage and heat dissipation under shock compression are investigated and the microscopic mechanics are revealed. Total deformation is decomposed into elastic and plastic parts based on the model of four decoupling configurations.

How does ZIF-8 dissipate shock waves?

We find that shock wave dissipation by ZIF-8 occurred by multiple processes: powder compaction, nanopore-collapse, and chemical bond-breakage. The shock energy absorbance in ZIF-8 is proportional to ZIF-8 thickness, allowing the prediction of the thickness of MOF layer needed to attenuate shock waves to a desired lower energy.

Does shock wave structure exhibit a distinguishable two-wave structure?

The shock wave structure for the orientation does not exhibit a distinguishable two-wave structure, namely elastic precursor wave and plastic wave, as shown in Fig. 5. The underlying mechanism was investigated in a previous study and is not discussed here. This work focuses on energy dissipation and storage of plastic work.

Does shock compression affect energy storage and dissipation in single copper crystals?

Conclusions MD simulations were employed to investigate energy storage and dissipation in two typical orientations of single copper crystals during shock compressions. The deformation at the atomic scale was decomposed into elastic and plastic deformation using a theoretical framework to decouple elastic-plastic deformation.

Is a shock wave a surface of discontinuity?

We have considered a shock wave as a surface of discontinuity and computed the entropy production using nonequilibrium thermodynamics for surfaces.
