The automobile engine rod may be a high volume production important element. The rod is that
the intermediate member between the piston and therefore the shaft. Its primary perform is to
transmit the push and pull from the piston pin to the crank pin, therefore changing the
reciprocatory motion of the piston into motion of the crank. Each vehicle that uses an indoor
combustion engine needs a minimum of one rod. Rod is subjected to additional stress than
alternative engine elements. This paper presents the modeling and analysis of rod through
engineering analysis idea with the assistance of CAD and CAE technique. Numerous outcome
parameters are flowed out from the analysis and listed in this worked out paper.
Simplified car model of the car industries is used to investigate the
aerodynamic parameters at high speed. Various CFD simulation
schemes are found to be most time and cost effective over the
experimental setups to obtain the drag parameters for enhancing the
fuel efficiency of a car. The present study makes an attempt to obtain
the drag coefficient with multiphase mixture K-epsilon turbulence
scheme model over a simplified car using ANSYS fluent which is in
close agreement with that of the existing experimental result.
Huge demand of sedan cars due to the economic developments in the society leads to increasing competitions in automobile sectors which undergo different testings to enhance the fuel efficiency and performance of these cars where vehicle aerodynamics plays avital role. Aerodynamics affects the performance of sedan cars due to change in parameters such as lift and drag forces at high speed. With the improvement in computer technology, manufacturers are looking at computational fluid dynamics(CFD) modelling of sedan carsinstead of wind tunnel testing to reduce the testing time as well as the research & development cost.In the present study, a simulation is done with ANSYS v15 taking Second Order Upwind Schemeto obtain the results of different flow parameters viz. drag force, drag coefficient, turbulent kinetic energy and wake flow structures over a benchmark test model- 3D Ahmed body which is a simplified sedan car.It is observed thatthe results of the present simulation with regard to drag coefficient are found to be in close agreement with the existing wind tunnel experimental results.This scheme can further be used to optimize the shape of the mid-range sedan carswith safety handling capabilities even at higher speeds and to enhance their fuel efficiency.
In wooden pulp production multiple types of machinery and equipment are used for refining, cooking and bleaching process. This scraper is made for pressure diffuser to make separation and pulp feeding bottom scraper is a component for outlet device in pressure diffuser. The new design is weldment based technological development which is to be replaced before this scraper was very bulky and by casting made. Few modifications and hub design to this rotary assembly new design give a compact and optimized solution with its validation. Sheet metal components are majorly used to assemble its material selection is based on the medium of pulp and ASME pressure vessel standards.
The present study deals with the simulation of turbulent flow modelling over an Ahmed body in the open test wind tunnel.Two types of meshing viz. tetra prisms (TP) and hex-prisms (HP)are used for domain discretization to solve the partial differential equations corresponding totwo equation turbulent models such as Realizable k-ï¥ (RKE) and Shear stress transport k-ï¥ (SST k-ï¥), analysed over the 25o slant Ahmed body. Numerical solutions are obtained for the drag coefficient, velocity profiles and turbulent wake intensities and are depicted through figures and tables.It is observed that SST k-ï¥, turbulence scheme with hex-prism mesh provides a comparatively better result than that of the existing schemes and hence can be used for the aerodynamic simulation studies.
This research work is focused on the Nickel particle reinforced resin based particulate composite. Composite samples are prepared with various volume percentage of filler content ranging from 0, 2,4,6,8 and 10% by simple economic hand layup technique. The mechanical testing revealed that increase in filler content enhanced the ultimate strength in both tension and compression. The composites have better compressive strength compared to tensile strength. The improvement in thermal conductivity for the composite samples confirmed well dispersion of Nickel fibres in matrix compared to pure resin samples.
