Abstract
This thesis is an experimental investigation on channel
type solar air heaters in an effort to evaluate and improve its thermal performance. Although many investigations were
made in this subject it appears that much is left to study
especially in the transition regime where the flow is neither
laminar nor turbulant. The experimental facility include flat
as well as corrugated absorber plates, three types of corrugat
ed plates were tested viz circular, rectangular and triangular.
In this study the system parameters include the air flow pas¬sage arrangement, interplate spacing, inlet air temperatures
together with number of glass covers. The corrugated absorber
plates were shown to enhance the efficiency of the collector
at high flow rates while retard it at lower flow rates. In
addition the circular corrugated plate is most efficient
since the eddies created.in sharp corners were minimum.
