Note: January 2009, In order that this could be used with
the grid-refinement module, SPINTO, the earler use of CONPOR
with its indicial arguments has been replaced by use of initial-
value patches such as:
** Vehicle body
patch(BODY1,inival,object,body1, 1,1)
coval(BODY1,prps,0.0,198)
wherein the arguments 'object' and 'body1' place the initial
values in the space indicated by the geometric arguments of
RSET(B,BODY1,,,,,)
This is a 3-dimensional Cartesian example in which a solid
body immersed in an unconfined flow is represented by means of
'porosities'. The turbulence of the flow is crudely represented
by a prescribed constant turbulent viscosity within the fluid,
together with a logarithmic law of the wall for skin friction.
The lower (south) boundary of the flow domain, representing
the road surface, is modelled as a moving wall.
An impression of the geometry can be gained by examining
the following sketch. |
