Abstract: The experimental and
numerical results of the heat transfer characteristics in the channel with
trapezoidal and V-shape wavy plates under constant heat flux conditions are
presented. The test section is the channel with two opposite wavy plates which
all configuration peaks lie in an in-phase and out-of-phase arrangements. The
experiments are performed for the Reynolds number and heat flux in the ranges of
1,500-2,500 and 0.5-1.2respectively. Effects of different
geometrical parameters of the wavy plate, wavy plate arrangement and heat flux
on the heat transfer characteristics are considered. Theturbulent mathematical model is employed to determine the temperature and velocity distributions. The wavy plate
has significant effect on the onset and the growth of the recirculation zones. Due to the presence of
recirculation zones, the convective heat transfer obtained from the channel with
the wavy plate is higher than that of the flat plate.
Keywords and phrases: heat transfer characteristics, wavy plate, heat transfer enhancement.
