Solar Fluid Heater With Electromagnetic Radiation Trap, Blaine Frank Parker May 1977

Solar Fluid Heater With Electromagnetic Radiation Trap, Blaine Frank Parker

Biosystems and Agricultural Engineering Faculty Patents

A solar fluid heater including a radiation trap for concentrating solar radiation which has been focused on or near a line at the center of a transparent pipe assembly containing the fluid to be heated is described. The pipe assembly may include one or more transparent pipes containing one or more sets of reflective fins which are disposed in direct heat exchanging contact with the fluid to be heated. The focused radiation entering the pipe assembly experiences multiple reflections off one set of reflective fins therein, thus concentrating the solar radiation. The reflective fins are made absorptive near the apex …

Modeling Soil Water Movement Into Plant Roots, D. C. Slack, C. T. Haan, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

Mathematical model was developed which describes uptake of water by plant roots as a function of leaf and soil water potentials. The model was used to estimate transpiration from corn grown in a controlled environment under soil drying conditions. The model predicted daily transpiration quite well for the period modeled.
