Safety and Security Studies and Modeling in Fluids

Transportation Systems, Accident Reconstruction, Disaster Models: The awareness and reaction to the vulnerability of transportation systems have stepped up significantly since the increase in terrorist activity over the last several years. Larger conveyance vehicles are especially susceptible to attack and have the potential for doing the most damage to people and surroundings in an accident of any type. The accident reconstruction and analysis in the current program aim to examine mechanical issues due to:

  1. Derailment
  2. Plastic deformation
  3. Rupture
  4. Initial impact
  5. Potential catastrophic failures (natural and manmade)

Modeling and Simulations

Nanofluid Simulations by Boundary Element
Method (PI: Wolf Yeigh)

With the advancement of semiconductor device technology, there comes an increasing demand for cooling. Efficient cooling is difficult. Low thermal conductivity of working fluids such as water, oil or ethylene glycol led to the introduction of nanofluids, which represent a novel approach to cooling. Nanofluid is a suspension consisting of uniformly dispersed and suspended nanometer-sized particles in base fluid.
