About Book

Hydrodynamics is concerned with the study and description of fluids in motion. The main emphasis is the teaching of the conservation laws of mass, energy and momentum. Flowing fluids possess kinetic energy. This energy can be converted into potential energy and vice versa. For ease of understanding, it is mostly steady states of incompressible fluids that are considered. To distinguish between the different states of fluid flow one must consider how the fluid reacts to a disturbance in the initial state. The principal laws and methods of mechanics are used in solving various problems of hydrodynamics. The practical applications of hydrodynamics are extremely diverse. Hydrodynamics is used in designing ships, aircraft, pipelines, pumps, hydraulic turbines and spillway dams and in studying sea currents, river drifts, and the filtration of groundwater and of underground oil deposits. This book provides comprehensive insights into the field of hydrodynamics and hydromagnetic. It attempts to understand the multiple branches that fall under this discipline and how such concepts have practical applications. It includes topics like hydromagnetic flow, hydrodynamics data, particle hydrodynamics, hydrodynamics systems, neural network modelling, heat conduction and laser-induced hydrodynamics. This book will give detailed information about both of the above mentioned topics along with other ones. Different approaches, evaluations and methodologies have been included in it. While understanding the long-term perspectives of the topics, the book makes an effort in highlighting their impact as a modern tool for the growth of the discipline. It will serve as a valuable source of reference for those interested in this field.
