The day/night cycle of an SUTThe solar updraft tower is a new-concept clean energy power plant for generating electricity from the sun. Sunshine falling on a greenhouse collector structure around the base of a tall chimney heats the air within it. The …
A Trombe wall is a sun-facing wall separated from the outdoors by glass and an air space. It consists a solar absorber (such as a dark surface) and two vents for air in the house to circulate through the space and carry the solar heat to warm the house…
ThermoregulationProject Lead The Way (PLTW) is the leading provider of rigorous and innovative Science, Technology, Engineering, and Mathematics (STEM) education curricular programs used in middle and high schools across the US. The PLTW Pathway To Eng…
The first stable version of Energy2D, an open-source and free heat transfer simulation tool made possible by funding from the National Science Foundation, is now available for download. The program can be installed as a desktop app, which can be used t…
Energy2D is our signature software for heat transfer and fluid dynamics simulations. Written in Java, it runs speedily either as a standalone app on your desktop or an embedded applet within a browser. It is actively being developed to meet the need of…
Run this simulation. The Kármán vortex street is a repeating pattern of swirling vortices caused by the unsteady separation of flow of a fluid over bluff bodies. It is named after the great scientist Theodore von Kármán who co-founded NASA’s JPL. This effect is observable in nature like in a stream, but you need some […]
The following are two Energy2D simulations that compare convection and conduction, which should run within this page if you have installed Java and Java applets are enabled with your browser. The first one shows the case of natural convection. The seco…
Computational fluid dynamics (CFD) uses numeric methods to study any natural phenomenon and solve any engineering problem related to fluid flow. It has been an indispensable tool for many engineers. Mature, powerful CFD products are available nowadays….
