Efficient modelling of complex multi-phase fluid-flows is one of the most common engineering challenges nowadays. The majority of the commonly used CFD solvers are based on Eulerian approaches (grid-b....
With the increase in customer expectations related to engine performance and vehicle NVH, it has become the need of the hour for automotive industry to continuously use state of-the-art designs. These....
A vehicle’s refueling system including components, which make up the onboard refueling vapor recovery (ORVR) system, must be designed to meet federally set evaporative hydrocarbon emission regulations....
In the present study a numerical investigation is performed by using computational fluid dynamics (CFD) aiming to figure out and maximize the separation efficiency of an oil separator by changing the ....
Powertrain and vehicle technology is rapidly changing to meet the ever increasing demands of customers and government regulations. In some cases technologies that are designed to improve one attribute....
Rotor Clutch sub-assembly is one of the very important sub-assemblies (S/A) of an automotive compressor as it delivers the required torque/power to run the compressor. It mainly consists of rotor and ....
Turbine housing in turbocharger is a critical part which must withstand severe cyclic mechanical and thermal load throughout its service life. The combination of thermal transients with mechanical loa....
Structural optimization has evolved vastly based on the development of computational based analysis – CAE. Structural optimization is usually a linear static response optimization because nonlinear re....
During the assembly process of planetary gears, the pinion shaft is initially pressed in to the planetary carrier and then staking is performed to fix the pinion shaft to the carrier. The main purpose....
As revealed from J. D. Power surveys, today most vehicle owners consider perceived quality as a direct indicator of the vehicle build quality and durability. [5] The problem has become more prominent ....
With strict government requirements for automobile fuel economy and global climate warming concerns, powertrain design becomes ever more challenging and complicated. New technologies come out daily, a....
Thin-walled objects, such as sheet metals or resin parts, are modeled as mid-surface in finite element analysis (FEA), where the extraction of mid-surface mesh is still problematic especially for obje....
A method for automatically generating hex-dominant meshes for Computational Fluid Dynamics (CFD) applications is presented in this article. Two important regions of the mesh for any CFD simulation are....
Computational Fluid Dynamics (CFD) tools play an important role in the early stages of vehicle aerothermal development. Arguably, the RANS (Reynolds Averaged Navier-Stokes) approaches are most widely ....
Leaf spring is a vital suspension component, such that the failure of leaf spring could cause fatal accidents. Due to frequent failures of leaf springs on vehicles, a method is developed to perform th....
