Experimental and Numerical Investigation of the Multiphase Flow and Heat Transfer in an Oil Jet Cooled Engine Piston

ABSTRACT The piston temperature has to be carefully controlled to achieve effective and efficient thermal management in the internal combustion engines. One of the common methods to cool piston is by injecting oil from the crankcase underside

A Transient, 3-Dimensional Multiphase CFD/Heat Transfer and Experimental Study of Oil Jet Cooled Engine Pistons

ABSTRACT This paper reports on a novel three-dimensional computational fluid dynamics (CFD) and heat transfer coupled methodology for analyzing piston cooling using oil jets. The method primarily consists of models of the fluid and the solid domains

PumpLinx EGM Thermal Modeling

ABSTRACT In typical positive displacement machines, the working fluid heats up as it is being displaced from the suction (low pressure) side to the delivery side (high pressure). This heating is caused by the losses from sources

Analyzing Noise and Vibration

ABSTRACT The simulation tools PumpLinx and Simerics MP can be used to predict, understand, and reduce noise and vibration in a fluid system. The following white paper provides procedures and guidelines for the above, including an example

Predicting Cavitation Damage

ABSTRACT Damage in fluid systems can occur for a variety of reasons. For any fluid system, with either gas or liquid, jetting and pressure waves can potentially cause damage.

How to Judge Pump Performance

ABSTRACT A common question with regard to virtual simulation of axial/centrifugal pumps is how to apply the results of Computational Fluid Dynamic (CFD) simulations to identify design weaknesses and improve on the design. Such optimization requires the

Effects of Leakage

ABSTRACT Modeling leakage gaps in Computational Fluid Dynamics (CFD) of pumps is critical in that parasitic leakage flow can severely degrade the performance and  in some cases even  lead to cavitation damage. Due to their complexity,  leakage

Automated Meshing with Binary Tree

ABSTRACT Automated binary-tree meshing is available in the Computational Fluid Dynamics (CFD) codes PumpLinx® and Simerics® MP to provide a fast and effective means of mesh generation without sacrificing accuracy. The purpose of this white paper is to
