| Summary: | A computational model is developed for the prediction of flow distribution in manifold
type flowspreaders. To address the difficulties associated with complex configurations of
manifold type flowspreaders and convergence problems, several numerical techniques are
used, including curvilinear coordinate-based calculations and domain segmentation. A 3D
curvilinear coordinate-based CFD code, called CMGFD, which can be used to calculate
laminar/turbulent flows in arbitrary geometries using curvilinear grids is adapted. To
support the application of the CMGFD code, a multigrid elliptic grid generation code,
MBEGG, was modified to generate multi-block curvilinear grids for the CMGFD code.
Validation of these methods is performed. The calculation of flow in liquid cooling
module manifolds shows that the predicted flow rate in each channel is in good agreement
with other numerical studies; the calculated cross-stream motions at different locations
agree well with experimental data for the turbulent flow modelling in a pipe junction, .
A Canfor manifold type flow spreader, which includes a tapered rectangular duct
with 560 tubes, is modelled. The effects of spreader recirculation rate and inlet flow
rate on the flow distribution have been considered. The computational results show
that the numerical tool has the ability to model the flow distribution of manifold type
flowspreaders. === Applied Science, Faculty of === Mechanical Engineering, Department of === Graduate
