Modeling reactive rarefied flows in Chemical Vapor Infiltration using Direct Simulation Monte Carlo
… composites. Gas-phase precursors flow into a porous fiber, react, and deposit to form the ceramic matrix. Deposition quality and rate are strongly influenced by surface reactions, depending on temperature, gas flow, and reactor pressure. This study applies a computational model to better …

Synthesis of a Highly Porous Polyethylene Membrane Support by Electrospinning- Optimization of the Parameters Involved
… the electrospinning of polyethylene to form a porous fiber mat,which was to be used as a membrane in pervaporation. For the first time,chlorobenzene combined with tetraoctyl ammonium bromide salt was used as asolvent for electrospinning polyethylene. Polyethylene fiber mat was generated by …

Acoustic and thermal packaging of small gas turbines for portable power
… silencer test rig. Acoustic liners based on porous fiber material were developed for both cold intake and hot exhaust gas silencers to reduce the broadband noise. The source noise simulations combined with the measured silencer noise reduction show noise levels below 50 dBA in all directions. …
