The Swiss Institute for Dryland Environmental Research

Department of Solar Energy and Environmental Physics

Chair: Prof. Faiman David


The Department of Energy and Environmental Physics is an interdisciplinary research group. It includes scientists with training in applied mathematics, mechanical engineering, meteorology, geography, chemistry, and physics. Research work at the department covers various aspects of the physical environment. These include solar energy utilization, the desert climate, the application of remote sensing methods for desert research, applied optics as well as more basic aspects of nonlinear dynamics and of thermodynamics as related to environmental processes, diffusion processes, the thermodynamics of irreversible processes, nonlinear dynamics, stochastic processes and statistics. The solar research activity includes solar thermal systems, electricity generation, radiation measurement, optical concentration of radiation, the stochastic analysis of energy storage, energy in buildings, system and component design, etc. Experimental solar research is conducted at the Ben-Gurion National Solar Energy Center. Work on diffusion processes includes nonlinear diffusion (specifically, phase change processes and diffusion of ions across membranes) and diffusion in porous media (e.g., of water in the soil). In irreversible thermodynamics, the research concentrates on the analysis of cyclic thermodynamic processes (`Finite Time Thermodynamics`) and on the study of phase change processes. The research on nonlinear dynamic systems focuses pattern formation in nonlinear systems on the perturbative analysis of small nonlinear disturbances. Members of the department collaborate with other research groups in the Institute on the mathematical and physical aspects of various research problems. The department provides consultation services, to government agencies and to municipalities with regards to the optimal utilization of solar energy in specific projects, and to industry on the development of novel solar devices, in particular, the design of novel radiation concentrators.
