Solid planar plates with area up to several square centimeters can be made parallel at controllable separations from ca. 0.1 ~if airborne dust is eliminated! to .500 mm. Apart from dust and surface roughness, which set the lower bound of plate-plate separation, there is no other fundamental constraint on the type of surface ~metallic or dielectric; opaque or translucent! that can be studied. Wh...

natural convection between vertical parallel plates occurs frequently in applications such as solar collectors and cooling of electronic instruments. the problem is a two dimensional developing buoyant flow. in this work, the two dimensional conservation equations are solved numerically for constant wall temperature and constant wall heat flux. the results for the local nusselt number at the du...

This paper studies unsteady laminar flow of dusty conducting fluid between parallel porous plates with temperature dependent viscosity. The fluid is acted upon by a constant pressure gradient and an external uniform magnetic field is applied perpendicular to the plates. The parallel plates are assumed to be porous and subjected to a uniform suction from above and injection from below. The visco...

A parallel plate type of mobility spectrometer provided with nuclear plates which are placed in a row in the middle area of collecting plates prior to sampling is examined for measuring the mobility spectra of radioactive charged aerosols. By this technique, it is able to record a ray tracks of radioactive substances collected on the surface of nuclear plates during and after

TRACT (Continue on reverse if necessary and identify by block number, ~.rcalculate the vacuum-field radiation pressure on two parallel, perfecting conducting plates. The modes outside the plates push the plates together, those confined between the plates push them apart, and the net effect is the well-known Casimir force. Implications of this result for the form of the Poynting vector in quantu...
