Abstract EN
A steady developing fluid flow and heat transfer through a wavy corrugated square cross-sectional passage (V-shaped and trapezoidal) was experimentally studied for a fluid with a Prandlt number of 0.7.
In the present study, the experimental investigation on the heat transfer and flow distributions in the channel with various geometry configuration wavy plates under constant heat flux conditions of 600 W/m² and 1100 W/m² is considered.
Effects of geometry configuration of wavy plates, wavy plate arrangements, and air flow rates on the temperature and flow developments are considered.
Reynolds number is range from (2.19 - 3.3) ×103.
The results indicated that the enhancement of heat transfer coefficient factors are obtained from the wavy plate structures were essentially independent of the operated heat flux.
The enhancement of heat transfer coefficient was ranged between the (1.036 to 1.062) and (1.042 to 1.066) for heat fluxes (600) W/m² and (1100) W/m² respectively for the V-shaped.
While the enhancement of heat transfer coefficient for trapezoidal it was ranged between the (1.052 to 1.077) and (1.058 to 1.082) for heat fluxes (600) W/m² and (1100) W/m², respectively.
The corrugated channel pressure drop was higher than the plain smooth surface.
The deterioration percentages of pressure drop for the corrugated plate when compared with that of flat plain surface was ranged between (15.4%) and (24.7%) for the V-shaped and (18.2%) and (27.5%) for trapezoidal with heat fluxes of 600 W/m² and 1100 W/m², respectively
