This book, titled “Heat Transfer to Non-Newtonian Fluids: Fundamentals and Analytical Expressions,” authored by Aroon Shenoy, offers a comprehensive exploration into the principles governing heat transfer in non-Newtonian fluids. Recognized for their widespread presence in various transport processes, non-Newtonian fluids necessitate more complex mathematical analyses compared to their Newtonian counterparts. The author presents methods of simplifying these equations and provides clear analytical expressions to address diverse heat transfer scenarios. Covering a broad spectrum including forced, natural, and mixed convection with and without porous media, the book also delves into both laminar and turbulent flow conditions, establishing criteria for transition between them in natural convection. Additionally, it examines heat transfer characteristics of non-Newtonian fluids ranging from inelastic power-law fluids to viscoelastic second-order fluids and mildly elastic drag-reducing fluids. Intended as a valuable resource for students and professionals in chemical engineering, material science and engineering, mechanical engineering, and polymer engineering, this publication serves as an essential guide in understanding the complexities of heat transfer involving non-Newtonian fluids.
