Thermal Hydraulic Criteria for Base-Triggered Vapor Explosion

The thermal explosion revisited.

The classical problem of the thermal explosion in a long cylindrical vessel is modified so that only a fraction alpha of its wall is ideally thermally conducting while the remaining fraction 1-alpha is thermally isolated. Partial isolation of the wall naturally reduces the critical radius of the vessel. Most interesting is the case when the structure of the boundary is a periodic one, so that t...

Coulomb explosion and thermal spikes.

A fast ion can electronically excite a solid producing a track of damage, a process initially used to detect energetic particles but now used to alter materials. From the seminal paper by Fleischer et al. [Phys. Rev. 156, 353 (1967)] to the present, "Coulomb explosion" and thermal spike models have been often treated as competing models for describing ion track effects. Here molecular dynamics ...

Criteria for Establishing Accurate Vapor Pressure Curves

We use standard thermodynamic relationships to demonstrate the accuracy of new vapor pressure measurements by using them in the calculation ofliquid-phase heat capacities and comparing the results with recently published experimental values. Results for the new alternative refrigerants Rl34a and R 123 are used as examples.

Thermal explosion in oscillating ambient conditions

Thermal explosion problem for a medium with oscillating ambient temperature at its boundaries is considered. This is a new problem in thermal explosion theory, not previously considered in a distributed system formulation, but important for combustion and fire science. It describes autoignition of wide range of fires (such as but not limited to piles of biosolids and other organic matter; stora...
