VISCOUS

Results of a CFD model created in VISCOUS,
a Windbox as used in a coal-fired power plant.

VISCOUS is one of our in-house codes and has been used since 1985 for a wide range of industrial flow problems. The code is fully three dimensional and is used in the following:

Complex subsonic flow fields - Newtonian or non-Newtonian*, laminar or turbulent. Turbulent flow fields use the well known k-epsilon turbulence model to account for small scale eddy structures even in relatively coarse grids.
Conjugate heat transfer problems.
Homogeneous, two-phase flows.
Body forces including gravitational, rotational, or electro-magnetic* may be present.
Internal heat sources may be present.
Mass sources and sinks may be specified.
Material properties such as density, viscosity, and conductivity may depend on position, temperature, concentration, and other properties.
Chemical species may react.*
Boundary conditions may be of the known value or known flux variety.
Distributed pressure resistances (screens/porous grids) may be modeled.
Heater cores and/or evaporator coils may be modeled, correctly accounting for the dependence of heat transfer on air velocity, fin temperature, fin spacing and fin geometry.
Time dependent flow fields may be computed using constant or varying boundary conditions.
