The boundary layer equations for plane, incompressible, and steady flow are 

$$\matrix{ {u{{\partial u} \over {\partial x}} + v{{\partial u} \over {\partial y}} = - {1 \over \varrho }{{\partial p} \over {\partial x}} + v{{{\partial ^2}u} \over {\partial {y^2}}},} \cr {0 = {{\partial p} \over {\partial y}},} \cr {{{\partial u} \over {\partial x}} + {{\partial v} \over {\partial y}} = 0.} \cr }$$

Increased use of continuous fibre reinforced plastics (CoFRP) is being seen in the automotive industry due to their high strength specific properties. The manufacturing process, however, is still expensive due to the number of critical steps and material cost. Cost reduction is being combated by computational modeling of the infiltration and curing process to predict void formation and other potential defects. The accuracy of these simulations is highly dependent on capturing the presence of the carbon sheets in the mold due to the large differences in permeability between flow parallel and normal to the fibre tows. This work presents a geometry based method for locally orienting the fibre and thickness direction for 2D extruded CoFRP components. The capabilities of these methods will be presented by comparing the fibre orientation prediction for two geometries (i.e., hat channel and double dome) using 3 difference draping schemes (i.e., 0°, 45°, 90°) against the results of a validated draping simulation developed in LS-DYNA.

A Model for Permeability in Fibre Reinforced Plastics

Systems, methods, and devices relating to a mechanism which can be used in gas cooling devices, pneumatic motors, turbines and other pressurized gas devices. A rotatable rotor is provided along with a number of hollow conduits that radially radiate from an exit port at the center of the rotor. The pressurized gas is injected into the mechanism at the inlet port(s). The gas enters the conduits and travels from the inlet port(s) to the exit port(s). In doing so, the gas causes the rotor to rotate about its central axis while the gas cools. This results in a colder gas at the exit port(s) than at the inlet port(s) due to an enhanced extraction of work, while maintaining a very low flow rate at the cold outlet.

We describe a study conducted to examine the influence of turbulence on the flow and heat transfer in graphitic foams. In this study, a Large Eddy Simulation (LES) model was used to characterize turbulence in the momentum and energy balances, and calculations were done to produce transient results of the velocity and temperature fields inside the spherical pores of the foam. The LES simulations enable excellent insight into the pore-level heat transfer mechanisms for the spherical void shape, and show that the heat transfer increases by a factor of 4.7 for an order of magnitude increase in the Reynolds number.
