The analytical and computational techniques used to simulate and study complex mathematical models have evolved significantly in recent years, which has widened the applicability of mathematical models in the investigation of real-world problems. Although mathematical models find application in nearly every area of engineering science, they are most extensively applied in basic scientific research in the areas of mathematical ecology, epidemiology, environmental systems, and the study of fluid flow problems. One of the basic aims of the book is to cover the recent developments in mathematical modeling in these areas of research. The articles presented in the book are aimed to provide the readers a comprehensive insight into the recent developments in various aspects of modeling and simulation of engineering systems from diverse areas of engineering, such as mechanical engineering, computer science engineering, biological engineering, environmental engineering, and so on.This book will serve as a reference for researchers, academicians, engineering professionals, policymakers, and graduate students interested in the modeling and computation of applied engineering problems. This book,for sure, equips the readers with the tools and techniques used for the formulation of a mathematical framework that bridges the gap between the core theory and experimentation in different areas of engineering sciences. A special emphasis of the book is on the mathematical modeling of the spread and control of some of the most burning issues of the current time, such as the control of the HIV pandemic, crop-pest management, rainfall-runoff modeling, and emission and impacts of global warming gases. This book is also intended to make the readers aware of the diversified applications of computational techniques to solve practical engineering problems, including analysis of Richtmyer–Meshkov Instability in shock-refrigerant bubble interaction, numerical investigation of wave pattern…
