Gadget Freak Case #197: Controlling Solar Water Flow
Gadget Freak 10/25/2011 19 comments To make his solar water heater more efficient, Paul Westaway put together a differential controller that turns on the pump when the temperature of the solar panel or woodstove coils is higher than the temperature in the storage tanks and turns off when the temperature is lower.

The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
