Conveying hard and the abrasive materials has been one of the major operational problems in industrial situations. The erosion of plant components, especially the pipe bends by abrasive solid particles of a fluid stream makes installation of pneumatic conveying systems a very costly affair for industry. Most users have either lived with the problem or have employed expensive bend materials to r...

Rheological characteristics of Al2O3, CuO and TiO2 nano particles were investigated in oil asthe base fluid at 1 and 2 wt.%. Constitutive relations for non-Newtonian fluid were discussedbased on the power-law model. Measured viscosities of each nanofluid were used to evaluatethe power-law and consistency index. Results indicated that the nanofluid viscosity decreasedby increasing the concentrat...

The aim of this research work is to evaluate the effects of coolant including nano- powder material for the cooling purpose in milling process and comparing the results with the conventional coolant. Generation heat and weak heat transfer reduces the tool life and also deteriorate surface roughness during milling operation. To overcome this problem, it is necessary to use coolant for cooling as...

In this paper, both linear and non-linear dynamics of a slender uniform pipe conveying pulsating fluid, which is axially moving in an incompressible are comprehensively studied. The vibration equations the system established by considering various factors, including coordinate conversion system, “axial added mass coefficient” describing additional inertia forces caused external Kelvin–Voigt vis...
