A non-linear flat-plate collector model

摘要: Abstract The analysis of a non-linear flat-plate collector is presented in which the overall loss coefficient assumed to be linear function temperature difference between fluid and environment. instantaneous performance collectors calculated using models terms three dimensionless numbers. For an parabolic solar radiation profile, average daily for constant inlet can further resulting expressions both are shown graphically. A method calculating characteristics from curve fitting experimental results so that predicted fits compared. In most circumstances, fit adequate.
