Construction

Room ventilation 1
You can analyze the air-conditioning performance in residential room, office and large space. The fluid analysis enable you to get the detailed distribution of the wind velocity, such as the numeric value in the specific area, and the temperature unlike the conventional thermal loading calculation. You can also calculate the gas concentration, the solar radiation effects and the dew condensation. STREAM is often used for the analysis of clean rooms which need the precise air-conditioning control.
Room ventilation 2
STREAM automatically calculates the heat generation by the sunlight using the solar radiation function. You can control the diverse parameters, such as transmission rate and absorptivity of the glass as well as the absorptivity of the surface of the object to which sunlight hits. Considering specific heat, you can also calculate the heat storage system which accumulates the solar heat in the daytime and uses it at night . STREAM can consider the thermal buoyancy like the natural ventilation caused by differences of temperature in a house.
Gas flow in a basement parking area
Considering fan arrangement in a basement parking area is essential for efficient ventilation. It is especially important for complicated configuration of the parking to avoid accumulated gas flow. STREAM has an index values to evaluate ventilation efficiency in addition to the regular computation of gas flow and gas concentration, so you can grasp the difference in efficiency of various fan arrangements and performances.
The analysis of the kitchen ventilation
A kitchen ventilation hood has achieved the various refinement to avoid letting of heat and odor outside. For a professional-use hood, the adjustment matched to the installation size is necessary. The numerical simulation method enable you to evaluate various examples such as the combination of different rising air volume by heat and ventilation air volume before manufacturing a prototype.
Air flow around buildings
In high rise community, wind change intricately and strong winds are often generated. The wind environment is often analyzed before construction since improvement after construction is very difficult and costly. STREAM achieves realistic analysis by importing the numerical map (GIS) data as well as the surrounding buildings.
Exhaust heat and the smoke from the building
You can analyze the diffusion of plant chimney gas and the exhaust heat from a cooling tower installed at office buildings. CFD is utilized to predict the gas concentration level and the efficiency of arrangement of a cooling tower and a Air-conditioner exterior unit.
A ventilation system
You can also evaluate a ventilation system performance. SC/Tetra is used for the analysis of complicated shape like the inside and outlet of an air-conditioner. STREAM is used for the analysis of surrounding airflow.
A painting booth
A painting booth needs the precise air-conditioning control as well as clean rooms. Furthermore, the airflow is also controlled so that paint reaches the paintwork precisely and floating paint does not reattach. STREAM can also analyze simulated particles, so you can calculate interrelated influence between airflow and particles, and the difference in the attaching locations by particle size.
Air flow around bridge
In vally-shaped terrain, atypical wind environment is often generated. When you build a construction in such a terrain, the analysis of wind effect to the environment and the wind pressure to the construction are important factors to be considered. STREAM can import terrain from the map data and calculate the wind pressure to buildings and bridges.
The water flow of a dam
STREAM and SC/Tetra can calculate the free surface analysis which calculate fluid surface shape by setting multiple properties to fluid. The free surface analysis can simulate the water accumulation and the flow of the dam.
A flow around the water gate
With the moving object function, STREAM also can calculate various phenomenon generated by closing down the water gate , such as the pressure fluctuation and the surface elevation.
