Film Coefficient in Hairpin Finned Heat Exchangers

Film Coefficient in Hairpin Finned Heat Exchangers is a focused engineering reference on the calculation and application of tube-side and annulus-side film heat-transfer coefficients in hairpin and finned heat exchangers. The book develops the subject from fundamental heat-transfer concepts to practical engineering design calculations. It covers Reynolds, Prandtl and Nusselt numbers; tube-side and annulus-side flow; laminar, transition and turbulent regimes; Sieder-Tate, Dittus-Boelter and Gnielinski correlations; hydraulic diameter; finned-annulus geometry; fin efficiency; overall surface efficiency; fouling; pressure drop; and overall heat-transfer coefficient. Special emphasis is given to finned hairpin exchangers, where fins influence flow area, wetted perimeter, hydraulic diameter, heat-transfer area, velocity, pressure drop and thermal performance. The book also includes worked illustrative calculations, a practical design procedure, common calculation mistakes, correlation-selection guidance and an examination-oriented formula sheet. Designed for B.Tech. and M.Tech. students, Ph.D. scholars, researchers and competitive-examination aspirants, this book can serve as a concise study, revision and engineering-design reference.
