TALK=T;RUN( 1, 1) DISPLAY This Q1 provides the input to PHOENICS which sets up a calculation of the quasi-steady flow around a walking man, represented by way of facets. The LVEL model of turbulence and PARSOL are used. The following pictures display some of the results: streamlines around the man1. longitudinal component behind the man,velocity contours, showing how the man's presence causes a wake of lowered-velocity air:
Various representations of the distance from the man's surface, used
for the calculation of turbulence:

Various other velocity contour diagrams from a similar laminar-flow
calculation:
