Development of a heat transfer coefficient for a single mist nozzle impinging on a heated thin sheet of Alloy 304 Stainless Steel using infrared thermography
A purpose built facility was designed, built and operated at the Advanced Thermal Hydraulic Research Laboratory, which is located at Oregon State University. This facility was used to heat a plate of Alloy 304 Stainless Steel to 800 °C and then cool the plate using a fine mist of water droplets. During the cooling process, the temperature of the plate was measured using an infrared camera. Using the experimental data an inverse calculation was performed to determine the heat transferred from the test plate. The experimental heat transfer data was used to develop a set of piecewise equations that describe the heat transfer from the test plate with a given flow rate over the four boiling regimes
