Being an engineer, I like tests – doing tests and reading about other peoples tests.

Tests of insulation, heat transfer, aerodynamic drag of add-ons, cooling tests, heating tests, freezing tests, MPG tests, …

This page is an index to the tests I’ve done and to interesting tests others have done.

Please let me know about interesting tests (or analyses) you have done or have seen.


Aerodynamic Tuft Test to show flow over van and roof racks.








Testing a window AC unit for van air conditioning.

How much efficiency is lost depending on how well the condenser is vented to the outside.
