Book Description
One of the challenging problems in the plasma spray technique is reproducibility of the coating quality. This problem is mainly associated with arc behavior inside the torch, plasma-particles interaction and coating built-up that includes plasma-substrate interaction. To improve the understanding of the same, in this study, three-dimensional models are developed to simulate the plasma arc inside the torch and plasma-substrate interaction under various operating conditions. The effects of arc current and gas flow rate on characteristics of the arc and temperature and velocity distributions both inside and outside of the torch are explained. Using the nozzle exit profile predicted from the plasma arc model, the Ar-N2 plasma jet and conjugate heat transfer between the plasma and substrate are simulated by using plasma-substrate interaction model. The effects of arc current, gas flow rate, stand-off distance, substrate material and environment around the substrate on the temperature and velocity fields of the impinging plasma jet and thermal flux to the substrate are clarified. This model is validated by comparing the results of present model with previous predictions and measurements.

Space and Astrophysical Plasma Simulation
Author: Jörg Büchner
Publisher: Springer Nature
ISBN: 3031118707
Category : Science
Languages : en
Pages : 427
Book Description
This book is a collection of contributions covering the major subjects in numerical simulation of space and astrophysical plasma. It introduces the different approaches and methods to model plasma, the necessary computational codes, and applications in the field. The book is rooted in the previous work Space Plasma Simulation (Springer, 2003) and includes the latest developments. It is divided into three parts and all chapters start with an introduction motivating the topic and its use in research and ends with a discussion of its applications. The chapters of the first part contain tutorials of the different basic approaches needed to perform space plasma simulations. This part is particularly useful for graduate students to master the subject. The second part presents more advanced materials for students and researchers who already work with pre-existing codes but want to implement the recent progresses made in the field. The last part of the book discusses developments in the area for researchers who are actively working on advanced simulation approaches like higher order schemes and artificial intelligence, agent-based technologies for multiscale and multi-dimensional systems, which represent the recent innovative contributions made in space plasma research.
