Abstract
In this study, the effect of corrugation angle on thermal performance of corrugated plate is numerically investigated with an aim to develop humidifying element. Numerical analysis was conducted for a range of corrugation angle (from $0^{\circ}/0^{\circ}$ to $60^{\circ}/60^{\circ}$ for equal angle and from $15^{\circ}/0^{\circ}$ to $15^{\circ}/60^{\circ}$ for unequal angle). Results revealed that both j and f factor increased as corrugation angle increased. Especially, f factor increased significantly at high corrugation angles. j and f factors of unequal angle plates and those of equal angle (obtained by averaging unequal angles) plates were approximately the same. The largest $j/f^{1/3}$, which implies the largest heat transfer rate per consumed power, was obtained at $15^{\circ}/15^{\circ}$. Existing correlations under- or over-predicted the present numerical results.
