The flow generated by a sphere descending uniformly in a linearly stratified diffusive fluid is
investigated numerically for different Reynolds (Re) and Froude (F) numbers. The
parameters used for the simulations were 10− 1≤ Re≤ 10 and 10− 2≤ F≤ 102, keeping
the Schmidt number, Sc (= 700, typical of sea water) fixed. The results demonstrate drag
dependence on viscosity and stratification, suggesting that changes in these parameters
would be intimately related to the phenomena of zooplankton vertical movement in the …
