THREE-DIMENSIONAL ELECTROPHORESIS CODE

WE PROPOSE TO DEVELOP A FLEXIBLE EFFICIENT COMPUTER CODE TO SIMULATE ELECTROPHORETIC SEPARATION PHENOMENA IN UP TO THREESPATIAL DIMENSIONS. THE CODE WILL ALLOW EITHER A CYLINDRICAL OR A RECTANGULAR GEOMETRY, AND WILL COMPUTE THE TIME EVOLUTION OF THE CONCENTRATIONS OF AN ARBITRARY NUMBER OF CHEMICAL SPECIES, AND OF THE TEMPERATURE. THE PH DISTRIBUTION, CONDUCTIVITY, ELECTRIC FIELD, AND FLUID MOTIONWILL BE CALCULATED EACH TIME STEP, AS FUNCTIONS OF THE CONCENTRATION AND TEMPERATURE DISTRIBUTIONS. USE OF NONUNIFORM MESHES AND FAST ACCURATE IMPLICIT TIME-STEPPING WILL YIELD ACCURATE ANSWERS AT ECONOMICAL COST. THE CODE WILL SUPPORT THE DESIGN AND INTERPRETATION OF LABORATORY ANDSPACE EXPERIMENTS AND OF COMMERCIAL SEPARATION DEVICES.
