A transient-state mathematical model for an ethanol basin solar still based on Spalding's work was developed. Driving … conductance (g) was obtained from an indoor experiment. Then productivity could be calculated. In order to validate the model an … ethanol basin solar still was tested under outdoor conditions. The model had RMSEs of 4% and 23% of the measured mean …

In this paper, a model of a micro-CHP (combined heat and power) system is developed and validated with laboratory … experimental results. The model is tuned to match steady state experimental test results, and validated with transient experimental … building model to evaluate the feasibility of the CHP system in the mid-Atlantic region as well as the Great Lakes region. The …
