Abstract

Study on the use twisted tape inserts in a parabolic trough receiver is presented.Use of twisted tape inserts significantly improves receiver thermal performance.Receiver thermal efficiency increases up to 10% with twisted tape inserts.At larger Reynolds numbers use of inserts degrades receiver thermodynamic performance.Entropy generation rates reduce up to 58% with the use twisted tape inserts.
