Independent Consultant, 1984 - Present.
- Developed interactive technical software products, involving all aspects of physical modeling, derivation, numerical algorithm design, code execution, testing and implementation.
- Conceived of a unique burn-rate formula for nitramines (RDX, HMX).
- Developed software for PC computational fluid dynamics to simulate specific combustion and flow processes, in particular in the areas of ignition, instability, and quasi-steady burning of solid propellants in interior-ballistic systems.
- Modeled compressed-gas driven air-bags; and rapid hydraulic actuation as in ballistic brakes.
- Expert in combustion system noise and blast noise, cavitation in liquid propellants, and chemically reacting flows in combustion systems such as fluidized beds.
- Developed catalytic cartridge technology for ultra-clean residential gas-burning heaters.
- Assisted in the conversion of lingo-cellulosic waste (such as biomass, olive pits, walnut shells, and creosoted wood) to activated carbon and gas energy, involving catalytic gasification of char.
- Invented a proprietary rapid activation/gasification technology for biomass-derived chars, for which a full-scale beta site gasifier has been constructed.
