Function(Pre)

As general-purpose fluid analysis software, scSTREAM provides core functions for solving basic structured grid thermal-fluid problems along with a multitude of specialized functions for simulating highly complex thermal-fluid phenomena.


Free Surface Analysis

scSTREAM can simulate the fluid's free surface shape. The MARS function enables the user to calculate how two fluids interact with each other. The Wave Generation function simulates wave propogation and attentuation on the free liquid surface. It includes use of permeable objects to simulate submerged breakwater, an important consideration in coastal engineering.

Moving Object Function

scSTREAM can move objects independently from its orthogonal grid. The fluid flow generated by the moving objects and the resultant thermal effects can be calculated simultaneously.

Panel Heat Conduction Radiation/Porous Solid

scSTREAM's panel function enables analysis of heat conduction, transmission and radiation (solar radiation) of thin panels. This function is helpful for reducing mesh size since the panel parts are not counted as mesh. STREAM can replace a cooling fin with a porous solid.

Particle Analysis Function

scSTREAM can calculate particle trajectories for general particles with mass and those that are chemically reacting. In the example, injection cooling with droplets is simulated using evaporating particles.

Dew Condensation/Evaporation Function

Interaction between water on a solid surface and the moisture in the air can be calculated. The user can predict instantaneous dew condensation as well as accumulated dew condensation. Moreover, the latent heat of evaporation is taken into consideration during the evaporation analysis.

Large Eddy Simulation (LES)

scSTREAM offers a variety of mean flow field turbulence model choices (e.g. traditional κ-ε and variants). However, if increased accuracy is needed for special cases, scSTREAM also offers a Large Eddy Simulation (LES) model with four subgrid scale models and two inlet variation options.

Sky Solar Radiation

scSTREAM contains sophisticated functions for simulating sky solar radiation. Solar sky radiation consists of direct radiation, sky radiation (component of radiation that is scattered by the atmosphere but reaches the ground), and reflected radiation. The simulation accounts for heat generated in shade due to sky and reflected radiation. It also includes a cloudiness coefficient that compensates for the radiation absorbed by clouds.
