Additionally, despite the system scale, gravity has a significant effect on the flow in the mini-channel and it can be exploited for the separation of phases.
The implemented approach is applied to simulate the shrinking of a Taylor bubble with a pure gas phase in a square mini-channel and to the competing mass transfer in a multi-component mixture.
We have achieved rapid chaotic mixing of two fluids flowing in a planar serpentine convergent divergent mini-channel, and analyzed the transient three-dimensional flow field and distribution of concentration.
Regarding the evaporator a simple correlation based on a homogeneous model [M.B. Bowers, I. Mudawar, Two-phase electronic cooling using mini-channel and macro-channel heat-sinks part II, flow rate and pressure drop constraints, ASME J Electron Packaging 116 (1994) 298–305. [1]] heat-sinks parto predIIt the pressure drop.
First, the optimization variables are the number and the diameter of mini-channels, and the mass flows for both heat sinks (hot and cold sides).
Capillary tubes are extensively used in several cooling applications like refrigeration, electronic cooling etc. Local pressure variation in adiabatic straight capillary tube (mini channel) is studied experimentally and numerically with R134a as the working fluid.
Many correlations had been and are being developed to predict the heat transfer coefficient in two-phase flow in a mini channel, particularly for new coolants investigated for their low environmental impacts.
The present work is focused on the effect irradiation behavior of infrared rays (IR) during gas liquid two phase flow consisting of thin liquid films inside a mini channel.
The aim of this paper is to present an inverse heat conduction method used for determining the local convective boiling heat transfer coefficient in mini channel for pure water, copper nanofluid with using three different concentrations of nanoparticles: 5 mg/L, 10 mg/L and 50 mg/L.
The optimised predictions for the highest heat transfer coefficient compared showed that the optimized heat transfer coefficient obtained from the correlation that was developed for a macro channel is close to that obtained from the correlation developed specifically for a mini channel.
