scSTREAM is widely used for analysis of architectural building climate control. The analysis can include outside air and thermal phenomenon that affect environmental issues.
Room Ventilation I
scSTREAM can be used to evaluate air-conditioning performance within a room in a house, office, or any large interior space. This fluid analysis calculates the distribution of the air velocity and temperature throughout the design space. This enables calculation of exact numerical values within any specific area. This is much more precise than the conventional thermal loading calculation. CFD enables inclusion/calculation of gas concentrations, solar radiation effects and dew condensation. scSTREAM is also often used for analyzing clean room designs which require precise air control.
Room Ventilation II
scSTREAM automatically calculates heat generation by sunlight using a solar radiation function. The user is provided with parameters to control solar radiation, such as transmission rate, glass absorptivity, and absorptivity of the object surface that is exposed to the sun loading. By including specific heat considerations, scSTREAM can be used to calculate performance of a heat storage system which accumulates solar energy during the day and uses it at night . scSTREAM can also consider thermal buoyancy such as the natural ventilation caused by differences in temperature throughout a house.
Gas flow in an Underground Parking Area
CFD is used for determining exhaust fan location and arrangement in an underground parking area. For complex parking area configurations it is especially important to avoid accumulated gas flow. scSTREAM generates an index value to quantify ventilation efficiency. In addition to standard computations of gas flow and gas concentration, the user can also easy determine the differences in efficiency for various fan arrangements and levels of performance.
A kitchen ventilation hood is designed to contain heat and odor. For a professional-use hood, the design and associated adjustments must be matched to the installation size. CFD enables design performance evaluation prior to manufacturing hardware.
Air flow around Buildings
High rise communities are subject to the intricacies of wind change. They can be subject to, as well as generate, strong winds. The wind environment should be analyzed prior to construction since making changes after construction is very difficult and costly.
scSTREAM can simulate accurate geometries by importing the numerical map (GIS format) for a specific building as well as the surrounding buildings.
Exhaust heat and Smoke
CFD can be used to analyze the diffusion of plant stack gas and the exhaust heat into the surrounding environment. CFD is used to predict the gas concentration at different altitudes. This analysis can be used to evaluate the efficiency of a specific cooling tower arrangement or the efficiency of an exterior air conditioning unit.
CFD is used to evaluate ventilation system performance. SC/Tetra is used when the analysis involves complicated shapes such as the inside and outlet of an air-conditioner. scSTREAM is used for the analysis of surrounding airflow and/or for simpler geometries.
A paint booth requires precise control of air flows similar to a clean room. Precise air flow ensures paint reaches the target part and is not washed away into the exhaust. scSTREAM can be used to simulate particles. This enables inclusion of coupling effects between the airflow and particles which ultimately determine where the particles will go.
Air flow around Bridge
Windy environments are induced in valley-shaped terrains. A wind analysis should be conducted whenever there is construction in these areas.
scSTREAM can import terrain geography from map data and calculate wind pressures on buildings and bridges.
Water Flow over a Dam
scSTREAM and SC/Tetra can perform free surface analyses which calculate fluid surface shape. The free surface analysis can simulate water accumulation and flow over a dam.
Flow around a Water Gate
Using the moving object function, scSTREAM can calculate the fluid flow field associated with closing down a water gate. This includes pressure fluctuations and the water surface elevation.
