Cooling Towers

Cooling Towers: Evaporative Cooling, Psychrometrics, Classification and Performance Characteristics is a comprehensive academic and practical guide to the fundamentals, analysis, classification, design principles, and performance evaluation of cooling towers. Developed for mechanical engineering students, researchers, educators, and practicing engineers, the book explains the complete cooling-tower process in a clear and structured manner. The book begins with the fundamentals of evaporative cooling and heat rejection, then develops the concepts of heat and mass transfer, sensible and latent heat transfer, psychrometrics, moist-air properties, wet-bulb temperature, enthalpy, and evaporative cooling. It further explores cooling-tower configurations, major components, fill arrangements, airflow patterns, counterflow and crossflow systems, and natural- and mechanical-draft towers. A major focus is placed on performance characteristics such as range, approach, effectiveness, heat-rejection capacity, air-to-water ratio, evaporation, drift, blowdown, cycles of concentration, tower characteristic, NTU, airflow, water loading, and fill height. The book also introduces the Merkel method, operating and equilibrium lines, and practical relationships used in cooling-tower analysis and design. With conceptual explanations, equations, engineering interpretations, worked examples, and examination-oriented material, this book provides a useful bridge between theory and engineering practice. It is intended to support classroom learning, competitive and university examinations, research work, and practical understanding of cooling-tower systems.
