Convective Mass Transfer Coefficient Measurement by Holographic and Electronic Speckle Pattern InterferometryMeasurements of the rate of transfer of volatile or soluble material from a solid surface of specified shape to a turbulent stream of gas or liquid flowing over it, due to forced convection and ...
In this present study an open sun and greenhouse drying of onion flakes has been performed to study the effect of mass on convective heat transfer coefficient. Three sets of experiments with total quantity of onion as 300, 600 and 900 g were done. The onion was continuously dried for 33 h...
The mass transfer rate at these interfaces is often described using a convective mass transfer coefficient. Analogous to the convective heat transfer coefficient, the convective mass transfer coefficient can be used to calculate the mass transfer rate by multiplying it ...
Re: Convective Heat Transfer - Heat Exchanger #7 Mark Guest Posts: n/a Hi Marco! The heat transfer coefficient depends on its definition. If you do not know the heat flow you have to calculate it by an energy balance on one side of the heat exchanger (mass flow * heat capacity ...
(kg/m3), c∗ is the liquid concentration on the membrane interface (usually denoted by cm; for harmony with the previous notations c∗ is used here, kg/m3), Jw is the water convective velocity (m3/m2 s), is the liquid film mass transfer coefficient (m/s), and δf is the film...
Thermophoretic diffusion coefficient (m2/s) H∗ : Height of the layer (m) H : Aspect ratio of the layer, equals H∗/ro∗ (dim-less) k : Effective thermal conductivity of the nanofluid suspension (W/m⋅K) LeB : Brownian Lewis number, equals =αf/DB [dim-less] LeT :...
Overall heat transfer performance The overall heat transfer performance of a lattice core sandwich panel can be described using three dimensionless parameters, the Nusselt number \(N{u}_{H}\), the Reynolds number \(R{e}_{H}\), and the pressure drop coefficient \({f}_{H}\). Choosing th...
The multi-phase volume of fluid model is used and the performance of mass transfer models is investigated for heat transfer coefficient, film thickness, bubble generation and liquid superheating. Results show that for 240 mL*min−1 of R-245fa at saturation pressure of 123.8 kPa at wall and ...

Note that the thickness of the laminar mass boundary layer decreases with increasing free air-stream velocity, with [Shahraeeni et al., 2012]. [8] Considering equation 1, the relative mass transfer coefficient, (−), as the ratio of the mass transfer coefficient (hereafter called MTC) ...
