Motion of nanoparticles in rarefied gas flows
Abstract. Solar cells have been made from hydrogenated amorphous silicon (a-Si:H) films. The films including Si nanoparticles by 3% in the volume fraction have been found to possess good properties. In order to find the method to control this volume fraction, the motion of Si nanoparticles in the rarefied flow of H2 and SiH4 is examined for a CVD (chemical vapor deposition) reactor by use of th...
متن کاملAiaa 2002-3297 Interference between Two Side-by-side Cylinders in Hypersonic Rarefied-gas Flows
Hypersonic rarefied-gas flows near two side-byside cylinders have been studied numerically with the direct simulation Monte-Carlo technique under transitional rarefied-gas-flow conditions (Knudsen numbers from 0.0167 to 10). Strong influences of the geometrical factor (ratio of distance between cylinders to cylinder diameter) and the Knudsen number on the flow structure (the shape of shock wave...
متن کاملSpectroscopic Study of REMPI for Rotational Temperature Measurement in Highly Rarefied Gas Flows
A measurement technique of thermodynamic variables with high sensitivity is strongly demanded for analyses of highly rarefied gas flows. REMPI (Resonantly Enhanced Multiphoton lonization) is a powerful optical tool because of its high sensitivity even in highly rarefied gas flows and ability to measure nonequilibrium among internal (translational, vibrational, and rotational) energy. In this st...
متن کاملTorque on a Rotating Ellipsoid in a Rarefied Gas
A particle, shaped as an ellipsoid of revolution and rotating about an arbitrary axis, experiences a torque in a rarefied monatomic gas because of the impact with the gas atoms. This torque is calculated for the case where the linear dimensions of the ellipsoid are small compared with the mean free path of the gas. The interaction of the gas atoms with the ellipsoidal surface is taken into acco...
متن کاملAerodynamics of a Spinning Cylinder in Rarefied Gas Flows
Conclusions The present study has investigated the problem of the elastic response of a generic space vehicle with degraded joints. The steppedbeam formulation based on elementary beam theory is employed for extracting modal parameters of a normalized generic space vehicle. Next, the modal superposition principle is used with a low damping value for obtaining the elastic response of the vehicle...
