filter may have a low enough pressure drop, therefore that option may also be tested in the future. The electrostatic precipitator was chosen for the current project because it does not suffer from the pressure drop problem. However, the low pressure of the Martian atmosphere, at 7 to 10 mbars, precludes the large voltages normally used in

Electrostatic Precipitator Reasoning Conventional filter limits flow due to high pressure drop and clogs quickly. Precipitator has very low pressure drop due to open geometry. One of the only viable possibilities for Martian atmosphere filtration available. Terrestrial precipitators are commonplace and achieve efficiencies upward of 99%. 20

Then, the electrostatic precipitators re-circulate clean air into the general airstream. Electronic air cleaners maintain a relatively high efficiency on particles in a range of .01 micron to 1 micron. Because of their inherently open cell design, electronic air cleaners create a low pressure drop that greatly minimizes fan horse power, and

SR-52 PROGRAM The SR-52 program is a two card program which provides a numerical solution to equation (3) for a log-normal particle size distribution. Card 1 is used to enter the data, calculate pressure drop, and calculate constants used in calculations performed using Card 2. Card 2 uses a trapezoidal rule numerical integration to solve

Thus, electrostatic precipitator (ESP) technology has become an important role to capture particulate emission in the diesel engine. Generally, ESP have a very low pressure drop and low electrical consumption [6]. Soot particulate matters are smaller than 10 μm in the
