The research activities of the considered group are based on numerical simulation of physics phenomena's and composed of three themes:
Plasma Physics: During the last few years, there have been a lot of activities in the field of a plasma physics because of its important role in understanding a plasma physics because of its important role in understanding the properties of different collective processes in space and astrophysical phenomena, as well as for many industrial and physical applications. In the proposed model, various nonlinear physical effects are considered on different plasma systems such as: relativistic, dispersive and non-dispersive medium, fluid temperature (for ion and/or for dust), dust charge fluctuation, superthermal, non-isothermality, non-thermality, vortices, and also contribution of higher-order nonlinearities. Therefore, our objective of the proposed model is to study nonlinear physical effects on the propagation, the instability, and the interaction of solitary waves, shock waves, and periodic traveling waves in plasmas and their application in astrophysical objects and laboratories.
Quantum Mechanics: Anharmonic oscillator potentials [AOP] have attracted a lot of attention from scientists in quantum physics fields during the last 50 years. Such potentials have interesting subjects in both from the viewpoint of theoretical and experimental studies and in terms of their applications in the various fields of physics, mathematics and chemistry. One such an example, studies of AOP contribute to the interpretation of vibration spectra of the diatomic molecules in chemical physics and in classical physics, which in turn explains the thermal expansion.
Fluid Mechanics: The aim of the research activities is to investigate numerically the coupled heat and mass transfer in a desiccant liquid air membrane energy exchanger as well as the effect of different operating parameters relative to humid air on the efficiency and performance of the process. The proposed numerical approach which is based on the energy and mass equations describes coherently the coupled heat and mass transfer processes taking place in the membrane based enthalpy exchanger with counter flow geometrical configuration. The proposed model take into account the saturated pressure by including it in the boundary conditions at the interface between the humid air and the desiccant solution.
