Development of a heat-transfer correlation for supercritical water in supercritical water-cooled reactor applications
… data, obtained in Russia, was analyzed and a new heat-transfer correlation for supercritical water was developed. This experimental dataset was obtained within conditions similar to those for proposed SuperCritical Water-cooled nuclear Reactor (SCWR) concepts. Thus, this new correlation, for …

Magnetohydrodynamic Heat Transfer for Fusion Energy
… of existing literature data to provide a heat transfer correlation for turbulent magnetohydrodynamic flows. Fluids used as breeder/coolant in fusion power plant blankets must provide adequate heat transfer of up to 10 MW/m2 within strong magnetic fields . Because the two most popular …

Aerothermal Sentencing for Manufacturing Variations on Turbine Blade Shrouds
… canonical 2D step flow. Since both the heat transfer enhancement and the step-normal component of velocity is largest in this quasi 2D (Q2D) aftchord region, a step heat transfer and loss correlation is developed using a parametric study on a Q2D model of the shroud endwall. The heat …

Specifics of forced-convective heat transfer to supercritical CO2 flowing upward in vertical bare tubes
Heat transfer in the forced convection regime of fluids at supercritical conditions has been studied extensively for the past 60 years. The dominant approach to summarize the experimental results was by proposing empirical correlations for the data within the investigated range of parameters. It …

Condensation in horizontal smooth round tube
… typically contains three regions: superheated (SH), two-phase (TP) and subcooled (SC) regions. However, since phase change requires temperature gradient, the first droplet in heat exchanger occurs as soon as the temperature of inner wall drops below saturation temperature even though the …

Experimental investigation of local air-side heat transfer coefficients of heat exchanger fins via an absorption-based mass transfer method
It is challenging to measure local air-side heat transfer coefficients (HTCs) with high accuracy due to the complexity of the involved surface geometries. An absorption-based mass transfer method has been developed to obtain local air-side HTCs. The method relies on measuring convective mass …
