Intense heat-mass transfer in a gas flow to condensation surface is studied with the consistent atomistic and kinetic theory methods. The simple moment method utilized for solving Boltzmann equation (BKE) nonequilibrium its condensation, while molecular dynamics (MD) simulation of similar used verification BKE results. We demonstrate that can provide steady profiles close those obtained from MD...

This study investigated the energy conversion of a thermoacoustic engine using wet regenerator for interconversion heat flux density and work density. According to first law thermodynamics, local can be described source corresponding gradient First, we analytically separated phenomena related water evaporation condensation. Thereafter, experimentally only gas, then that The data obtained were c...

Very low temperatures stress a circuit breaker in a complex manner. Mixed-gas circuit breakers were developed for use at temperatures as low as -50C. These breakers utilize a gas mixture of SF6 and CF4 or SF6 and N2 to prevent condensation of the SF6 gas and have been type tested at -50C to ensure travel characteristics, operating times, and gas tightness are acceptably affected. Today’s mixed-...
