Experimental Studies on Swirling Flow in a Vertical Circular Tube
Swirling flows are related to the spiral motion in the tangential direction in addition to the axial and radial direction using several swirl generators. These type of flows are used in combustion chambers to improve flame stability, heat exchanger to enhance heat transfer coefficients, agricultural spraying machines and some vertical pipes to move slurries or transport of materials. However, o...
متن کاملEntropy Generation in Laminar Fluid Flow through a Circular Pipe
A numerical solution to the entropy generation in a circular pipe is made. Radial and axial variations are considered. Navier-Stokes equations in cylindrical coordinates are used to solve the velocity and temperature fields. Uniform wall heat flux is considered as the thermal boundary condition. The distribution of the entropy generation rate is investigated throughout the volume of the fluid a...

متن کاملVisualization of Swirling Gas-solid Flow Pattern in a Horizontal Pipe Based on Wavelet Analysis of Pressure Signals
The wavelet transform is applied to experimental pressure fluctuations in swirling gas-particle two-phase flows in this paper, to identify and interpret flow pattern transitions in both Fourier and physical spaces. From randomlike pressure fluctuations the characteristic of swirling gas-particle twophase flows can be extracted, and the relationship between the wall pressure fluctuation and the ...
