Air Circulation Under Reduced Atmospheric Pressures

<p>The control of heat exchange is vital for plant life in off-world, low pressure,</p> <p>greenhouses. The ability to control this process was limited by methodology and</p> <p>technology. Mathematical models, based on classical mechanics are created to enhance</p> <p>our control capabilities. Data is collected using various sensors placed inside the Low</p> <p>Pressure Test Bed (LPTB) Chamber at Kennedy Space Center. Data from those sensors</p> <p>became non-linear at various pressures below 25 kPa. We introduced mathematical</p> <p>calibration corrections and found that sensor data linearity could be extended to a greater</p> <p>range of pressures. These calibration corrections allow for sensor calibration corrections</p> <p>in operational environments that differ from the environment of calibration (normal Earth</p> <p>atmospheric pressure).</p>
