Consider two concentric, infinitely long cylinders. The cylinders are oriented such that the center-line is along the z-axis, and the radii exist in the r-direction. The inner cylinder has a radius of ra and the outer cylinder has a radius Tb. The inner cylinder rotates with an angular velocity of w whereas the outer cylinder is stationary. There is no pressure gradient applied nor gravity. The fluid contained between the cylinders is assumed to be Netwonian, incompressible, isotropic and isothermal....

Consider two concentric, infinitely long cylinders. The cylinders are oriented such that the center-line is along the z-axis, and the radii exist in the r-direction. The inner cylinder has a radius of ra and the outer cylinder has a radius rb. The inner cylinder moves in the positive z-direction with a velocity W while the outer cylinder is held stationary. The fluid contained between the cylinders is assumed to be Netwonian, incompressible, isotropic and isothermal. The flow of the fluid...

Navier-Stokes Equation:
An incompressible Newtonian liquid is confined between two
concentric cylinders of infinite length—a solid inner cylinder of
radius RA and a hollow outer cylinder of radius RB. The inner
cylinder rotates at angular velocity ω and the outer cylinder is
stationary. The flow is steady, laminar, and two-dimensional in the
r-θ plane. The flow is rotationally symmetric, meaning that nothing
is a function of the coordinate θ. The flow is also circular so
that ur=0 everywhere.

Consider two concentric, infinitely long cylinders. The cylinders are oriented such that the center-lines are along the z-axis, and the radii exist in the r-direction. The inner cylinder has a radius of r, and the outer cylinder has a radius rb. The inner and outer cylinders are stationary. Gravity exists in the negative z- direction, whereas a constant pressure gradient exists in the positive z-direction. The fluid contained between the cylinders is assumed to be Netwonian, incompressible, isotropic and isothermal....

Fluid is Non-Newtonian.
(3) Consider the steady laminar flow between the coaxial cylinders shown below. The inner cylinder rotates with angular velocity 2 and the outer cylinder is stationary. The no-slip condition applies at the inner and outer cylinder surfaces and we are considering the cylinders to be very long in the 2-direction hence we may ignore edge effects near the top and bottom surfaces. - R2 Assume that gravity is negligible, v, is zero and that are zero for...

The viscosity of a fluid is to be measured by a viscometer constructed of two 75 cm long concentric cylinder. The outer diameter of the inner cylinder is 15 cm, and the gap between the two cylinders is 0.12 cm. The inner cylinder is rotated at 200 rpm, and the torque is measured to be 0.8 Nm.

A viscometer is an instrument for measuring the viscosity of a fluid. In a simple form, it consists of two concentric cylinders, with the outer cylinder fixed and the inner cylinder free to rotate. The space between the two cylinders is filled with the fluid in question, and the torque required to rotate the inner cylinder at a constant speed is measured. One such device consists of two 21.0-cm long cylinders, one 15 cm in diameter and the other 15.4...
