Yg. Chesnokov, RESISTANCE FORCE EXERTED ON A SPHERICAL GAS BUBBLE AND A SPHERICAL DROP, Russian journal of applied chemistry, 66(8), 1993, pp. 1349-1351
An approximate analytical expression was given for the resistance coef
ficients of a spherical gas bubble (or a drop) moving in liquid (in th
e absence of SAS) at any value of Reynolds number.
