fluctuating velocity मीनिंग इन हिंदी

But his smooth delivery and fluctuating velocity confuse overeager hitters.
The fluctuating velocity field gives rise to fluctuating stresses ( both tangential and normal ) that act on the air-water interface.
When a flow is turbulent, one observes a randomly fluctuating velocity field superimposed on a mean flow ( contrast with a laminar flow, in which the fluid motion is ordered and smooth ).
This change is balanced by the mean body force, the isotropic stress owing to the mean pressure field, the viscous stresses, and apparent stress \ left (-\ rho \ overline { u _ i ^ \ prime u _ j ^ \ prime } \ right ) owing to the fluctuating velocity field, generally referred to as the Reynolds stress.
