Role of Electric Field on Diffusion Coefficients for Weakly Coupled Plasma

1. Introduction

Thermophysical properties of complex systems are dynamically investigated by simulation and in laboratories to study the complex system a microscopic level. It has played a fundamental role in the field of science and technology. Thermophysical is a combination of thermodynamic and transport properties. Thermodynamic defines the equilibrium condition of complex systems such as heat, temperature, enthalpy, entropy, pressure and density. Whereas, transport properties described the energy, mass and heat flow of complex systems. It includes diffusion, shear viscosity and thermal conductivity. In this chapter, our motivation is to explore the effect of electric field on diffusion coefficient in 3-D weakly coupled dusty plasma by using molecular dynamics (MD) simulations. First, it defines the basics of plasma and dusty plasmas (DPs) in physics. The existence of DPs in nature, laboratories and industries is explained in detail. The significance of DPs is discussed by their possible applications in industry, laboratory, space and tokomak. The general theory and mechanism of DPs, its main parameters and characteristics are discussed. Next is the introduction of computer simulation techniques used in this study, and a historical overview of molecular dynamics (MD) simulations and the model and method are explained in detail. The purpose and motivations of the presented work are to be obtained from simulation data of diffusive transport properties in the presence of varying electric field at numerous DPs’ parameters, together with previous work that has been done to date. It provides necessary problems, justifying the current work performed with the contribution for this chapter.
