The validation procedures for standard- and micro-scale methods were carried out.
The prediction for flow boiling heat transfer coefficients was broken down into separate macro- and micro-scale methods.
These data were carefully analyzed and compared against 12 two-phase frictional pressure drop prediction methods, including both macro- and micro-scale methods.
The meso- and micro-scale methods are also being developed in parallel with the continuum theory-based conventional CFD techniques-using finite volume method (FVM) and finite element method (FEM).
By coupling CALPHAD method with micro scale solidification model, the predicted solidification path for different composition or cooling rates and the eutectic fraction of Al Si Mg alloys agree well with the experimental results.
However, for systems working at the micro-scale, design methods developed for evaluating heat transfer in macro-scale evaporators are not appropriate for passages with hydraulic diameter of the order of 1 mm and below.
Using some experimental data on bending of a nickel titanium micropillar the applicability of the present method in the micro scale is studied.
The present multiscale model, where the KLG method treats the micro scale process of diffusion and reaction in the liquid film, is found to yield accurate predictions at a reasonably small computational cost.
An effective method based on micro scale modelling for the determination of overall pore throat size distribution (PSD) by injection of colloidal particle suspensions into engineered porous media with monitored inlet and breakthrough particle concentrations is developed.
A different homogenization method is applied at the micro scale, where the cell problem is solved numerically using the Finite Element Method (FEM) program.
At a micro scale it means that many communities simultaneously have unmet needs and underused capacities.
