Abstract

A suspension system is an important part of a two wheeler since it reduces the effects of travelling over rough ground, leading to improved ride quality, and increase in comfort due to substantially reduced amplitude of disturbances. Recently, vibration isolation and reduction techniques have become an integral part of machine design/vehicle design and hence the need for accurate measurement and analysis of mechanical vibration has grown. In this study vibration measurement has been carried out in two different suspension systems of two wheelers (nitrox & normal) using accelerometer with Fast Fourier Transforms(FFT) on DEWEsoft software......

Abstract

Non-traditional machining processes such as Wire Electric Discharge Machining (WEDM) are increasingly been employed to machine difficult-to-machine materials. Monel 400 an alloy of Nickel and Copper is taken in this study and it is cut through Wire Electric Discharge Machining process. It is utilized mainly in corrosion resistant applications. Further, the process parameters are optimized to get the desired machining conditions which can improve the quality of machining. Design of Experiments is done through Central Composite Design (CCD). Response Surface Methodology (RSM) and Genetic Algorithm (GA) which is an evolutionary algorithm are the techniques employed for the optimization of parameters in WEDM......

Abstract

The location of traffic accidents on arterial roads of Makassar-Sidrap precisely at KM 173 to KM 174 from Makassar. This research aims to analyze the physical characteristics of roads, traffic sign and road markings, and (3) anatomy of a traffic accident on a road km 173 to km 174 from Makassar, using qualitative and quantitative description. The physical is complying with request IHCM 1997, except for the width of traffic lanes still requires special to handle. The degree of the saturation 0.39, free flow speed average was 67.8 km/hour with the level of service B. Traffic sign and road markings have not been adequate, there are no warning signs that should be installed an accident-prone area that could potentially be the cause of traffic accidents.....

Abstract

Development of shopping centers have an impact on the increase in traffic volume resulting from the pull and vehicle movement generation. This research aimed to analyze the condition of the road network services of Urip Sumohardjo in Makassar and projection of the traffic volume to the presence of Nipah Mall. Data obtained by recording and counting directly at the research locus and the document data obtained from relevant agencies. Analysis of road service processed using Microsoft Excel based Indonesian Highway Capacity Manual (IHCM) 1997. The results showed the existing level of service at the level of the current "C" is stable, the speed can be controlled by traffic with the degree of saturation of 0.74 is the threshold performance good road...........

Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 07 ~ Issue 4 (April 2017)

Abstract

This paper deals with the optimization of bluff bodies and analysis of fluid flow behaviour around bodies using CFD. Three test cases of bluff bodies; mainly two-dimensional rectangular body, radial rectangular shape and bullet shaped body were considered in this paper. Their shapes were optimised to achieve aerodynamic body shape using drag coefficient as main criteria. The other aerodynamic characteristics like formation of different eddy loops due to eddy viscosity, lift force coefficient and pressure force with Mach number were also investigated. It is concluded that aerodynamically; bullet shaped body is best among all the cases.

Keywords: Aerodynamics, Bluff body, Computational Fluid Dynamics (CFD), Drag coefficient, Eddy viscosity, Mach number, Optimization.

International Journal of Computational Engineering Resaerch, Volume 07 ~ Issue 4 (April 2017)

Abstract

The accurate estimation of reference evapotranspiration (ETo) plays a pivotal role in water resources planning and management studies. The present study was attempted to estimate the reference evapotranspiration (ETo) using three temperature based methods namely, Blaney-Criddle method, Thornthwaite method and Hargreaves-Samani model and three radiation based methods namely, Turc method, Priestly-Taylor model, and FAO - 24 Radiation Model for Mohanpur area, Nadia district, West Bengal. ET estimates of the above mentioned methods were then compared with FAO Penman - Monteith (FAO-56 PM) method, which was considered as the standard method of ETo estimation, to check the capabilities of different models to predict ETo for the study area.............

Keywords: Reference evapotranspiration, Mohanpur, FAO-56 Penman-Monteith method, water resources.

Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 07 ~ Issue 4 (April 2017)

Abstract

We develop an analytical theory for the interaction between waves and currents induced by breaking waves on a depth profiles. Here we examine the effect of friction on the rip currents and so are not particularly concerned with frictionally determined rip currents. The near shore is characterized by the presence of breaking waves, and so we develop equations to be used outside the surf zone, based on small-amplitude wave theory, and another set of equations to be used inside the surf zone, based on an empirical representation of breaking waves. Suitable matching conditions are applied at the boundary between the offshore shoaling zone and the near shore surf zone. Both sets of equation are obtained by averaging the basic equations over the wave phase. Thus the qualitative solution constructed is a free vortex defined in both shoaling and surf zone where in the surf zone the free vortex is perturbed by a long shore component.

Keywords: Wave-current interactions, set down, set up, surf zone, shoaling zone, breaker, matching conditions and rip current.
