... of this study is to extend fundamental knowledge about heat transfer and fluid dynamic processes in conduits pertinent to sCO 2 with an emphasis on flow direction and inclination effects. This paper presents the study on effects of gravity, buoyancy on sCO 2 flow at temperatures near and away from the pseudo...

... trends in boiling heat transfer data and as a means for developing methods to predict boiling heat transfer. Results are presented that demonstrate how a genetic algorithm and deep learning can be used to extract heat flux dependencies of a binary mixture on wall superheat, gravity, Marangoni effects...

...E. Da Riva; D. Del Col A three-dimensional volume of fluid (VOF) simulation of condensation of R134a inside a 1 mm i.d. minichannel is presented. The minichannel is horizontally oriented and the effect of gravity is taken into account. Simulations have been run both with and without taking...

...Rishi Raj; Jungho Kim A pool boiling regime map demarcating the boundary between the surface tension and buoyancy dominated boiling regimes is developed based on heater size and gravity. For large heaters and/or high gravity conditions, boiling is dominated by buoyancy, and the ebullition cycle...

...Amit Kumar; Kevin Tolejko; James S. T'ien A detailed, two-dimensional, laminar, flame spread model over a thin solid is solved in both a normal gravity downward spread configuration and in a microgravity quiescent atmosphere configuration. The radiation transfer equation is solved using discrete...

... investigated the linear stability of a core-annular flow (CAF) in a horizontal pipe with less viscous fluid located in an annulus surrounding the more viscous fluid. Viscosity stratification and surface tension effect were considered but gravity effect was excluded. Windows of parameters were identified...
