Here we present a latent heat storage device which is used to provide “quick/supplemental” heat to the vehicle's conventional heating system. First, we present data from actual in-vehicle cold weather tests. Data are presented for heater and defroster performance tests, emissions tests and cold start tests after extended soaks. Secondly, heater performance predictions are made using a computer simulation program. Finally, the actual heater performance results are compared with the computer simulation.

Here we present an analytical model, written in general terms, which predicts the trajectory of a spherical particle/droplet placed in a uniform fluid stream. The model is compared to an experiment in which three millimeter diameter polypropolyene spheres (specific gravity = 0.91) are dropped in a uniform airstream (velocity varies from 0.9 to 3.8 m/s). Agreement between the two suggests the model incorporates all the important physics and thus should be useful as a design tool.
