Abstract :
In this paper, the top heat losses from a 60 vee corrugated solar collector with single glazing have been investigated. An approximate
method for computation of glass cover temperature and top heat loss coefficient has been followed. A modified equation from Akhtar
and Mullick’s relation was proposed. The predicted values of the glass cover temperature and the top heat loss coefficient were compared
with the results obtained by iterative solution of the energy balance equations over a wide range of operating conditions. A good accuracy
is provided by the proposed equation which is recommended to be used in the energy analysis of the present configuration.
