Applied Mathematics And Modeling For Chemical Engineers, Third Edition
Description
Applied mathematics is the use of mathematical concepts and methods in various applied or practical areas, including engineering, computer science, and more. As engineering science expands, the ability to work from mathematical principles to solve and understand equations has become an ever more critical component of engineering fields. New engineering processes and materials place ever-increasing mathematical demands on new generations of engineers, who are looking more and more to applied mathematics for an expanded toolkit.
Applied Mathematics and Modeling for Chemical Engineers provides this toolkit in a comprehensive and easy-to-understand introduction. Combining classical analysis of modern mathematics with more modern applications, it offers everything required to assess and solve mathematical problems in chemical engineering. Now updated to reflect contemporary best practices and novel applications, this guide promises to situate readers in a 21st century chemical engineering field in which direct knowledge of mathematics is essential.
Readers of the third edition of Applied Mathematics and Modeling for Chemical Engineers will also find:
Detailed treatment of ordinary differential equations (ODEs) and partial differential equations (PDEs) and their solutions
New material concerning approximate solution methods like perturbation techniques and elementary numerical solutions
Two new chapters dealing with Linear Algebra and Applied Statistics
Applied Mathematics and Modeling for Chemical Engineers is ideal for graduate and advanced undergraduate students in chemical engineering and related fields, as well as instructors and researchers seeking a handy reference.
