Direct solar drying; indirect solar drying; PCM drying; Ther- mal efficiencyAbstract
The expressions for crop and moist air temperatures, drying rate
and efficiency of indirect solar drying with phase change material (PCM)
storage systems in quasi-steady state conditions have been derived. The
analysis is based on the basic energy balance for the system. A computer
model has been developed to predict the performance of the solar dry-
ers. Experimental validation of the thermal model has been carried out
by using modified heat transfer coefficients. Internal heat and mass
transfer coefficients have been evaluated with PCM for March 24, 2014 in
Varanasi, India. A fair agreement has been observed between theoretical
and experimental results by using the modified internal heat and mass
transfer coefficients.
