Study of shear thinning and shear thickening in 2D fluids
... Fluids which are made up of more than one type of fluid particles, i.e., these fluids are heterogenous in nature. For these fluids, the relationship between shear stress and shear rate may not be Newtonian type. Several interesting Complex fluids have been synthesized in labs across the world as the ...

Summary abstracts and conclusions
... inlet temperature, pressure, mass flow, heat flux, buoyancy and flow direction were investigated. An M-shape velocity distribution develops across the tube with increasing heat flux, due to the property variations and the buoyancy. This phenomenon becomes more evident as the heat flux and as x/d in ...

Bernoulli`s equation
... To express the pressure force on the sphere in terms of the fluid velocity, we use Bernoulli’s theorem for steady potential flows, H = p/ρ + kuk2 /2 = constant, ignoring gravity. At r = a the fluid pressure, p(θ), therefore satisfies p(θ) 1 2 ...

... There is a pressure P4 in the pipe #4 due to the placement of pipe #4 in the vertical direction because the flow is opposite to the gravity in pipe #4. So, the voltage supply V4 is placed in the circuit due to the analogy. The positive end of the V4 is connected to the point A. The current produced ...
