Mist/Steam Cooling in a Heated Horizontal Tube—Part 1: Experimental System
Tao Guo,Ting Wang,J. L. Gaddis +2 more
TL;DR: In this article, a fundamental experimental program has been developed to study the heat transfer mechanisms of mist/steam cooling under highly superheated wall temperatures, where fine water droplets (3 {approximately} 15 microm in diameter) with the saturated steam at 15 bars were used to improve the airfoil cooling significantly for the future generation of turbine systems.

Modeling of heat transfer in a mist/steam impinging jet
TL;DR: In this paper, an impinging mist flow is modeled as heat flow to a spherical cap for a time dependent on the droplet size, surface tension, impact velocity and surface temperature, the model is used to interpret experimental results for steam invested with water mist in a confined slot jet.
