Industrial smoke contains various hazardous particles, ash namely to be one of the various substances. The cyclone separator is a specially designed device used to separate the ash particles from the stream of air. The stream of dirt and air mixture flows in two vortexes, the inner vortex and the outer vortex, this device in turns acts as a scrubber and the ash particles get collected down in the ash collector whereas the fresh air stream is released by the device. To increase the efficiency, i.e. to increase the ash collecting capacity of the device, we have tried to compare a classical cyclone separator with the one we created which has protruding surfaces internally and the comparative analysis is done using the CFD software ANSYS R16.0.
Present work is an attempt to develop a simulink model of tool wear by machining of Bearing Steel (62 HRC) using cubic boron nitride (CBN) tool. The available mathematical model in the scholarly literature is used to make the simulation model using MATLAB software. Three components of tool wear adhesive wear, abrasive wear & diffusion wear are considered separately for their modeling and later modeling of total wear is done. Variation of tool wear is studied with respect to cutting speed. The developed simulink model is capable to do the similar type of study by changing the workpiece and tool material combination.
This paper describes the thermal analysis of fluid flowing through a sudden expansion of pipe. Also the relation between velocity and pressure has been taken into consideration with changing the expansion ratio. All analysis has been done by using ANSYS 14.5 in axi-symmetric 2D model, using K-eplison equation for the turbulent flow. Pressure and velocity contour has been shown in this paper and fluid is considered as AIR.
The heat transfer rate from a solid horizontalrectangular fin and fins with of same geometrical dimension embedded with different number of same circular perforations under natural convection is numerically investigated. The parameters considered in this investigation are the geometrical dimension of fins, perforationdimension of fins with different number of same circular perforation. A comparison between heat transfer rates of the solid fin with different number of the circular perforated finsis presented. It is found that the heat transfer rate of solid horizontal rectangular fin is low as compared to different number of circular perforated fin and the lateral spacing between perforation decreases which increases heat transfer coefficient. Here in this experimental analysis of fins we compute the three different value of heat transfer coefficient lies on three different places first one is on flat perforated surface h ps ,second one is on fin tip h t , thirdly at inner perforated surface of perforation h pc , here (h ps ≠h pc ≠h t) for computing the value of total heat transfer rate of each fin to get the overall effectiveness of the fin. The problem of this study was numerically solved and results are plotted through mat lab software.
