Rayleigh benard cell
WebUsing a cell with horizontally mounted membranes, volume flux was measured as a function of gravitational geometry. Water was placed on one side of the membrane. The opposite side of the membrane was exposed to either aqueous glucose solutions, with densities greater than water; or aqueous ethanol, less dense than water; or ethanol—glucose—water … WebOct 25, 2002 · PCR in a Rayleigh-Bénard convection cell.
