A Textbook of Turbo Machines by Govinde Gowda and Nagaraja: A Review

Turbo machines are devices that transfer energy between a fluid and a rotor, such as turbines and compressors. They are widely used in various engineering applications, such as power generation, aerospace, and refrigeration. A textbook of turbo machines by Govinde Gowda and Nagaraja is a comprehensive and updated book that covers the theory and design of different types of turbo machines, such as axial, radial, and mixed flow machines.

The book is divided into 15 chapters, each covering a specific topic related to turbo machines. The first chapter introduces the basic concepts and definitions of turbo machines, such as velocity triangles, degree of reaction, specific speed, and efficiency. The second chapter deals with the thermodynamics and fluid mechanics of turbo machines, such as the first and second laws of thermodynamics, entropy, enthalpy, stagnation properties, and flow regimes. The third chapter discusses the dimensional analysis and similarity laws of turbo machines, such as the Buckingham pi theorem, Reynolds number, Mach number, and similarity criteria.

The fourth chapter covers the cascade theory of turbo machines, such as the blade element theory, cascade geometry, cascade performance, and losses. The fifth chapter explains the axial flow turbines, such as the impulse and reaction stages, velocity diagrams, stage loading, blade design, and off-design performance. The sixth chapter describes the axial flow compressors, such as the stage characteristics, degree of reaction, stall and surge phenomena, blade design, and off-design performance.

The seventh chapter deals with the radial flow turbines, such as the impulse and reaction stages, velocity diagrams, stage loading, blade design, and off-design performance. The eighth chapter covers the radial flow compressors, such as the centrifugal compressor stage characteristics, slip factor, diffuser design, surge margin, and off-design performance. The ninth chapter discusses the mixed flow turbines and compressors, such as the diagonal flow machines, velocity diagrams, stage loading, blade design, and off-design performance.

The tenth chapter explains the steam turbines, such as the classification of steam turbines, nozzle design, impulse and reaction stages, compounding methods, reheat factor, losses and efficiency. The eleventh chapter describes the gas turbines,

such as the classification of gas turbines,

Brayton cycle,

regeneration,

intercooling,

reheating,

combustion chamber design,

losses and efficiency.

The twelfth chapter deals with the hydraulic turbines,

such as the classification of hydraulic turbines,

Pelton wheel,

Francis turbine,

Kaplan turbine,

draft tube design,

cavitation phenomenon,

losses and efficiency.

The thirteenth chapter covers the hydraulic pumps,

such as the classification of hydraulic pumps,

losses and efficiency.

The fourteenth chapter discusses the wind turbines,

such as the classification of wind turbines,

horizontal axis wind turbine,

vertical axis wind turbine,

blade element theory,

power coefficient,

tip speed ratio,

losses and efficiency.

The fifteenth chapter reviews the recent trends and developments in turbo machines,

such as the transonic and supersonic flows,

shock waves,

boundary layer control,

blade cooling techniques,

active control methods,

and renewable energy sources.

The book is written in a clear and concise manner,

with numerous examples,

illustrations,

tables,

and charts to aid understanding.

The book also includes several solved problems at the end of each chapter to reinforce learning.

The book is suitable for undergraduate and postgraduate students of mechanical engineering who want to learn about turbo machines in depth.

The book is also useful for practicing engineers who want to update their knowledge on turbo machines. 061ffe29dd
