Ippolit Stepanovich Gromeka

Born Jan. 27 (Feb. 8), 1851; died Oct. 13 (25), 1889. Russian physicist.

Gromeka worked at Moscow University after his graduation there in 1873. He began working at the University of Kazan in 1880 and became a professor there in 1882. Gromeka laid the groundwork for the modern mathematical theories of capillarity (1879), so-called screw flow, and flow with cross circulation (1882), which took on great practical importance in hydraulic engineering. He also studied the unsteady motion of viscous fluid (1882), the propagation of shock waves in fluid in elastic tubes (1883), the vortex motions of fluid on a spherical surface (1885). and a number of cases of equilibrium of an ideal gas.
