On the Generation of an Intense Temperature Gradient Through a Modified Shock Tube Hydrodynamics for a Possible Continuous Sterilization Process

Abstract

Abstract Data on hydrodynamics of carbon dioxide in shock tube can be presented as a main opportunity to apprehend and establish sterilization treatment process. Here, a modified and axi-symmetric shock-tube model has been developed to simulate shockwave propagation and reflection after rapid bursting of two diaphragms separated initially with a relaxed fluid. It has been demonstrated that the given model is capable of accurately simulating, locating, and measuring shock and expansion wave propagation and reflections as well as estimating the thermodynamic preconditions that can lead to prompt sterilization.
