چکیده
Boiling conjugate heat transfer is an active field of research encountered in several industries, including metallurgy, power generation and electronics. This paper presents a computational fluid dynamics approach capable accurately modelling the flow phenomena during immersion quenching: process which hot solid immersed into liquid, leading to sudden boiling at solid–liquid interface. The adopted methodology allows us couple regions with very different physics, using partitioned coupling. energy equation describes solid, while Eulerian two-fluid governs fluid’s behaviour. We focus on film regime, yet also consider natural convection, nucleate transition boiling. A detailed overview given, analytical description between all three phases. latter leads derivation temperature Biot number, considering both These are then employed assess solver’s In comparison previous research, additional regimes, extra interfacial forces separate equations for each phase, phase change their interface, employed. Finally, validation conducted against published experimental numerical results.

Ultrahigh Flux Thin Film Boiling Heat Transfer Through Nanoporous Membranes.
Phase change heat transfer is fundamentally important for thermal energy conversion and management, such as in electronics with power density over 1 kW/cm^2. The critical heat flux (CHF) of phase change heat transfer, either evaporation or boiling, is limited by vapor flux from the liquid-vapor interface, known as the upper limit of heat flux. This limit could in theory be greater than 1 kW/cm2...
متن کاملHeat Transfer Mechanisms During Flow Boiling in Microchannels
The forces due to surface tension and momentum change during evaporation, in conjunction with the forces due to viscous shear and inertia, govern the two-phase flow patterns and the heat transfer characteristics during flow boiling in microchannels. These forces are analyzed in this paper, and two new nondimensional groups, K1 and K2 , relevant to flow boiling phenomenon are derived. These grou...

In this investigation, it has been confirmed that the heat transfer coefficient in boiling solutions are regularly less than those in p...
متن کاملFluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer
The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...
