Journal ArticleDOI
A study of frost growth and densification on flat surfaces
TL;DR: In this paper, a semi-algebraic model was proposed to predict the variation of the frost layer thickness and mass with time, based on mass and energy balances within the layer, assuming the frost as a porous medium.
Journal ArticleDOI
A study of frost nucleation on flat surfaces
TL;DR: In this article, a mathematical model for the heterogeneous frost nucleation on smooth surfaces was put forward based on the classical nucleation theory, which showed a good level of agreement.
Journal ArticleDOI
Thermodynamic comparison of Peltier, Stirling, and vapor compression portable coolers
TL;DR: In this article, the authors compared the performance of four small-capacity portable coolers that employ different cooling technologies: thermoelectric, Stirling, and vapor compression using two different compressors (reciprocating and linear).
Journal ArticleDOI
Liquid entrainment, droplet concentration and pressure gradient at the onset of annular flow in a vertical pipe
TL;DR: In this article, an isokinetic probe was employed to measure the local mass fluxes of gas and entrained liquid droplets in the core region; pressure gradient was also measured.

TL;DR: In this article, a rotary active magnetic regenerator (AMR) and detailed numerical model of it are presented, which consists of 24 regenerators packed with gadolinium (Gd) spheres rotating inside a four-pole permanent magnet with magnetic field of 1.24 T.
