This special issue took this opportunity to invite researchers to contribute their original research work and review articles to this Special Issue on “Recent Trends in Coatings and Thin Film: Modeling and Application” to be published in Coatings. The goal of this Special Issue was to address challenges and current issues that either advance the state-of-the-art of experimental, numerical, and theoretical methodologies, or extends the bounds of existing methodologies to new contributions that are related to coatings and thin film containing whichever, magnetic, multiphase, material science, nanotechnology, surfaces, interfaces, and mechanical sensing properties. In response to the call for papers, a total of 58 papers were submitted for possible publication. After comprehensive peer review, only 27 papers qualified for acceptance for final publication. The rest of 31 papers could not be accommodated. The submissions may have been technically correct, but were not considered appropriate for the scope of this special issue. The authors are from 17 geographically distributed countries, such as China, Spain, Romania, Turkey, Saudi Arabia, Pakistan, Malaysia, Abu Dhabi, UAE, Vietnam, Korea, Taiwan, Thailand, Lebanon, Egypt, India, and Kuwait, etc. This reflects the great impact of the proposed topic and the effective organization of the guest editorial team of this Special Issue.

Polytropic Model

A linear stability analysis of a simple polytropic model for the solar wind dynamics within the framework of a magnetohydrodynamic equilibrium configuration is theoretically proposed. The simplistic analysis is based on the model developed based on the data available from the Advanced Composition Explorer (ACE) spacecraft mission. A unique form of dispersion relation is derived by coupling the adiabatic and polytropic processes in the limit of ideal gas approximation for the solar wind gas in accordance with the standard Fourier technique. Applying usual variable-separation methodology on the dispersion relation, we obtain the linear growth rate of the fluctuations. It is seen that the growth rate is an explicitly nonlinear function of the variable polytropic index (α) and radial position (r) with respect to the considered center of the Sun. Numerical analyses are carried out to understand the physical insight of the growth profiles of the fluctuations. It is shown that the growth is maximized near the solar corona, where α ∼ 1, relative to that observed elsewhere in the entire solar plasma system. The source for this growth may be attributed to the free flow of energy coming from the dynamic equilibrium of the solar plasma itself. As compared with existing model predictions, our results are qualitatively capable of reproducing the average behavior of the solar wind fluctuation and stability behaviors on the astrophysical scales of space and time.
