On the Nonlinear Electrostatic Waves in a Plasma: An Application in Compact Astrophysical Objects

Summary

In the last years, the study of relativistic degenerate dense magnetoplasmas has become one of the most important activities of quantum plasma physics because of their vital role in the investigation of the compact astrophysical objects. Therefore, in this project, the electrostatic travelling wave structures are investigated in degenerate dense magnetoplasmas consisting of relativistic degenerate inertialess electrons and positrons, as well as nondegenerate inertial cold ions.

Study of the anharmonic oscillator potentials

Summary

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.

Numerical Simulation of the Heat and Mass Transfer in Membrane Based Enthalpy Exchanger

Summary

Renewable energy opportunities in water desalination constitute a promising new way of producing potable water, better and cleaner than those produced from burnt oil. Desalination is a water-treatment process by thermal processes that separates salts from saline water to produce potable water or water that is low in total dissolved solids. In this context, Membrane desalination is a promising process, especially for situations where low temperature solar, geothermal, waste, or other heat is available. The membrane based enthalpy exchangers which can recover both sensible heat and moisture, are very efficient for heat and moisture recovery in humidification and dehumidification processes especially in sea water desalination systems.
