2 and 4 to shear bands caused by adiabatic heating
Early SBSL studied attributed these spectra to blackbody emission which is in line with adiabatic heating model.
Instead of simplistic adiabatic heating model, the sonochemical processes can be considered in terms of more sophisticated plasma chemical approach allowing explaining the new effects in sonochemistry as well as in sonoluminescence.
As adiabatic heating
also affects HPP performance, these points should be considered when planning experiments:
To quantify the effects of friction and adiabatic heating on the mechanical response of the material, numerical simulations have been performed.
Since we are using the reference stress-strain response as input, we assume that any adiabatic heating is implicitly included in this input response.
The cause of this believed to be due to adiabatic heating occurring at higher deformation rates resulting in significant temperature rises in the polymer during stretching as suggested by Buckley et al.
Adiabatic heating is due to the nature of the deformation resulting in heat dissipation which depending on the temperature and strain rate may produce a temperature rise in the specimen during stretching.
Hillmansen (7) demonstrated, by increasing the crosshead speed in a series of dog-bone tensile tests, that adiabatic heating eventually destabilized drawing.
To study the destabilization of tensile drawing by high-rate adiabatic heating, Leevers et al.
This adiabatic heating
effect complicates the study of fracture as a function of test speed .
c) adiabatic heating
involved orientational crystallization (8).
Other mechanisms for failure include cold drawing and adiabatic heating
(viscous flow): neither of these will be considered for developing a selective grinding process.
For polyethylene, the thermal diffusion equation included terms for the heat of fusion generated during crystallization and for adiabatic heating
resulting from the applied pressure.
Therefore, the field strength and the internal heat generation rate in the gasket were estimated using calorimetry or adiabatic heating
of the gasket while measuring the temperature rise (16).
