Effect of Gap Length and Partition Thickness on Thermal Boundary Layer in Thermal Convection
Entropy, 2023 Two-dimensional direct numerical simulations of partitioned thermal convection are performed using the thermal lattice Boltzmann method for the Rayleigh number (Ra) of 109 and the Prandtl number (Pr) of 7.02 (water).

The connection between air flow regime and heat transfer in the boundary layer of the brake disc cooling unit [PDF]
E3S Web of Conferences, 2023 The boundary layer of the air flow blowing the surfaces of the brake mechanism prevents heat transfer from heated surfaces. The obtained analytical dependences of the velocities` and temperatures` distribution in the boundary layer represent the field of

Physical Model of a Single Bubble Growth during Nucleate Pool Boiling
Fluids, 2022 A simplified physical model of a single bubble growth during nucleate pool boiling was developed. The model was able to correlate the experimentally observed data of the bubble’s growth time and its radius evolution with the use of the appropriate input ...

Solution of Boundary Layer and Thermal Boundary Layer Equation
Asian Research Journal of Mathematics, 2018 We studied equation of continuity and boundary layer thickness. The Blasius and Falkner equations are studied in order to investigate the guess values in various boundary layer thicknesses, and Falknar-skan equations shows when velocity profile has a point of inflection in case of accelerated and decelerated.

Heat Transfer by Thermals in the Convective Boundary Layer [PDF]
, 1989 The convective boundary layer (CBL) develops in the atmosphere if turbulence generated by buoyancy due to upward heat flux from the surface dominates relative to turbulence generated by mean shear. The CBL extends from the surface up to an inversion layer at height z i . Above the inversion, the fluid is stably stratified. Turbulence in the mixed layer
