Kern's Process Heat Transfer

Ann Marie Flynn, PhD, the first female Manhattan College graduate to return to the school as a full-time faculty member, served as the department chair and graduate program director during her 27-year tenure in the chemical engineering department where she received multiple awards for teaching and leadership. She used Donald Q. Kern's text almost exclusively during the 16- year period when she taught Heat Transfer, and undertook the writing of the 2nd edition to bring Kern's straight forward approach towards heat exchanger design to the next generation of engineers. Toshihiro Akashige, B.S. Chem. Eng., is a graduate from Manhattan College and currently enrolled in a PhD program for chemical and biomolecular engineering at the New York University Tandon School of Engineering. He particularly enjoyed process heat transfer class taught by Dr. Flynn and eventually joined in co-authoring this textbook with a hope that Dr. Kern's design methodology will help many other students and future engineers gain comfort in the technical knowledge of heat exchangers. Louis Theodore, MChE and EngScD, is a retired professor of chemical engineering (50 years). He is the author of several publications, including Fluid Flow for the Practicing Chemical Engineer, Thermodynamics for the Practicing Engineer, Mass Transfer Operations for the Practicing Engineer, and Air Pollution Control Equipment Calculations. Dr. Theodore is also a contributor to Perry's Chemical Engineers' Handbook.

"Congratulations to the authors for keeping Kern's classic heat transfer book alive and relevant. This new edition is a wonderful contribution to the chemical engineering literature. As with the classic first edition, the new book can be used as either a reference book for the practicing engineer or a textbook for the undergraduate/graduate engineering student. This book was masterfully updated by a team of experts."—Rita L. D'Aquino, Former Senior Editor of Chemical Engineering Magazine
