Welcome to the Ariel ABMC Fluid Dynamics Laboratory

In the Ariel ABMC Fluid Dynamics Laboratory, we focus on the complex interactions between fluids and structures using experimental and numerical methods.

​

Specific Research Interests:

  • Fluid dynamics in biomedical and energy systems using experimental, numerical and analytical methods.

  • Hemodynamics and vascular remodeling in the cardiovascular system and of cardiovascular devices;

  • Flow control and optimization of fluid and gas in energy systems, including fuel cells, hydrogen generators, microturbines, fuel and gas pipes, microfluidics, the flow of Swarmbots, etc.

  • Numerical methods for simulating fluid and structure interaction in models involving complex geometry, unsteady flow and moving boundaries

ABMC Hydrogen Production On-demand by a Pump Controlled Hydrolysis of Solid Hydride

Michael Zolotih, Alex Schechter and Idit Avrahami Ariel University, Israel This movie presents a new type of hydrogen generator for "on-demand" use with hydrogen-based fuel cells. Hydrogen is produced in a catalytic hydrolysis reaction of sodium borohydride. The proposed generator is lightweight, has high energy density, efficient, portable, easy to use, refill, and clean. The described system consists of two main chambers, the upper chamber with sodium powder and the lower reaction chamber with a solution of water and catalyst. A peristaltic pump regulates the flow of water solution through a designated channel in the upper chamber with sodium borohydride and saturated solution drips into the reaction chamber. This system is significantly lighter and requires much less operating energy than other similar generators. To maintain constant H2 flow rate levels, the system controls continually solution temperature and H2 pressure in the reaction chamber. The mechanical and control systems were designed for long working periods and at different conditions, and with capabilities for restarting after prolonged rests. Experiments were carried out to prove system reliability and efficiency to allow commercial applications with a fuel density of 1296Wh/kg. This device has great potential for a variety of military, vehicle, and portable device applications.
