TRANSPORT PROCESSES OF PARTICLES IN DILUTE SUSPENSIONS IN TURBULENT WATER FLOW--PHASE II

An increased understanding of particle motion in a turbulent fluid field has been achieved both in an analytical and in an experimental sense. Analytically, a theory simplified by the restrictive constraints of isotropy has been developed. Assumption of a reasonable particle energy spectrum allowed calculation of various statistical quantities important in the determination of the particle's turbulent motion. By such an analysis three characterizing parameters were found. Two describe inertial effects due to the particle's size and density. The crossing of the particle from one region of correlated fluid turbulence to another by virtue of its free fall velocity is described by the third. Analysis of the particles' behavior in the turbulent flow gave a three dimensional characterization of their motion.
