Shape and Wall Effects On Particle Drag In Liquids

The poster presentation consists of*comparing terminal velocity and drag coefficient data from our experiments with literature correlations/theoretical relations for terminal settling conditions under no wall effects(large column dia data) *comparing data collected under strong wall effects with literature correlations.Our final data of terminal velocities would include non-spherical particles of shapes of cubes,cones,ellipsoids,cylinders of  various cross-sections(circular,square,triangular,rectangular) and plates.The particle materials are metals,glass and plastics.Five Newtonian liquidsand several concentrations of CMC solutions and five glass columns are being used.
