The Effect of the Corrugation Height on Temperature Distribution in Primary Surface Recuperator for 30 kW Microturbine

Rilrada Sangsawang, Thanate Matum, and Udomkiat Nontakaew
Abstract—This research paper presents the effect of the corrugation height of the corrugated foils on temperature distributions in the counter-flow primary surface recuperator (PSR). The flow channel of study is in the form of rectangular channel with semicircular ends. The primary surface recuperator is designed based on the microturbine recuperator requirements and the 30 kW microturbine operating parameters. The exact solutions for temperature distribution, obtained from the thermodynamic modeling with the help of the analytical method and Laplace Transform, for both fluids are solved and are verified by computational fluid dynamic program package. The results show that the corrugation height of the foils has direct effect to the convective heat transfer coefficient, the Nusselt number, and also the recuperator effectiveness.

Index Terms—Effectiveness, heat exchanger, microturbine recuperator.
