Double Fano resonance optical devices for solar energy harvesting.

Brenda Dana, Physical Electronics, Faculty of Engineering

Brenda is a PhD student at Tel Aviv University. In this study, Brenda and her advisor proposed and numerically demonstrated a geometrically simple asymmetric IMI structure able to support a double FFR spectral line-shape. The overall line-shape is determined by the periodicities of the gratings at the metal-insulator interfaces of the structure, and also by their unit-cell configuration. The location of the resonances is related to the gratings periodicities as was shown by the research simulations. The asymmetry parameters are determined mainly by the shape of the unit-cell of each grating. Here, a straight forward mapping between these shapes to the asymmetry parameter does not exist, and so to get a desired exact line-shape one needs to use optimization procedures in the available parameters space.

Improving efficiency of bio-fuels productions from macroalgae cultivations by means of intensive grow for enhancement of the photosynthetic process

Oz Habiby, School of Mechanical Engineering, Faculty of Engineering

Thanks to the generous support of BMI we were able to design and built in the past few months two experimental systems. First, a laboratory experiment in the Prof. Liberzon's laboratory has been designed to examine the influence of different light parameters on the growth rate of the seaweed culture, mimicking the intensification of the offshore system. Controlling the light source we plan to prove that the grow rate of the algae can be enhanced and the bottleneck in the cycle from marine biomass to bio-diesel product can be breached. Second, an off-shore field experimental system has been designed to prove the concept of offshore marine agriculture.

First‐order model of Free‐Jet hydrodynamic Evolution for Heat Transfer prediction and design in solar cells and desalination applications

Ron S. Harnik, School of Mechanical Engineering, Faculty of Engineering

Ron is a M.Sc. Student under the supervision of Dr. Herman D. Haustein and has won several awards and grants noting his academic achievements. In light of the increase in incident heat flux, failure to manage waste heat reduces conversation efficiency of highly focused CPV and leads to cell deterioration. The goal of this study is the development of a simple free jet cooling model via deconstruction of the flow. The method involves simulating (DNS) a free jet’s three stages: pipe evolution, relaxation and contraction in flight, impinging heat transfer; validated by comparison to previous work and experiments. The flow and heat transfer models are constructed by identifying inherent self-similar scales (for simple relations), and serve as tools for designing a modular impinging jet array which cools various size CPV cells.
