Figure 1: Copy data from Energy2D.Since a few users asked if the simulation data in Energy2D can be exported to other applications such as Excel, I have added a feature to the app for extracting virtual sensor data as multi-column time series data. For…
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…
It is my goal to make the Energy2D software a powerful simulation tool for a wide audience. Last week I have added some engineering examples and blogged about them.Last night I came up with an idea for simulating mantle convection, the slow creeping mo…
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…
A thermostat is a controller that maintains a system’s temperature near a fixed point. The simplest thermostat does this by switching a heater or AC on and off to maintain the desired temperature (known as the bang-bang control). I spent a couple of da…
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…
Last month, North Carolina’s Senate passed a bill that would have required the state’s Coastal Resources Commission to base predictions of future sea level rise along the state’s coast on a steady, linear rate of increase. This has sparked controversie…
Metals feel colder because they conduct heat faster, not because they are really “colder.” This is often a misconception from students. A very simple IR experiment may dispel this misconception by visualizing what is going on when you touch a piec…
