Bent tube design used in a high temperature heat exchanger using a FE analysis and RSM

Acoustic resonance and pressure drop through a staggered tube bundle in a compact heat exchanger

“…Power systems that include gas turbines are now designed to run at higher temperatures and higher pressures than ever before, and heat management systems containing heat exchangers such as recuperators, intercoolers, and advanced cooling air coolers have been included to improve efficiency [1,2]. A compact heat exchanger with small tubes has been considered to be an appropriate candidate for use at high pressures and temperatures, and such a heat exchanger could be compact, light, and cause little pressure loss [3][4][5][6][7].…”
