The potential of this work is based on consideration of wear volume map for the evaluation of abrasive wear performance of polytetrafluoroethylene (PTFE) and PTFE composites. The fillers used in the composite are 25% bronze, ...

The ability of an artificial neural network model, using a back propagation learning algorithm, to predict specific fuel consumption and exhaust temperature of a Diesel engine for various injection timings is studied. The ...

The friction and wear performance of pure polyetheretherketone (PEEK) and 30% carbon fiber-reinforced PEEK composite were comparatively evaluated under dry sliding and water drops lubrication. The sliding experiments were ...

Performance of centrifugal fans with unshrouded impellers strongly depends upon complex configuration of the asymmetrical flowfield in the axial direction, which is highly unsteady. The flowfield, in turn, is considerably ...

In this paper, thermal systems are simulated and analyzed with a new approach. Thermal system design equations can be obtained as a nonlinear algebraic equation system and then this nonlinear equation system is converted ...

Centrifugal fans are being widely used in many industrial applications. However, when handling gases with temperatures exceeding 800 degrees C, the use of centrifugal fan impellers are of particular interest since the ...

Tests were performed on a six cylinder, direct injection, turbocharged Diesel engine whose pistons were coated with a 350 mu m thickness of MgZrO3 over a 150 mu m thickness of NiCrAl bond coat. CaZrO3 was employed as the ...

One significant issue concerning the impingement heat transfer with a jet array is related to the so-called "crossflow", where a local jet performance is influenced by the convection of the confluence from the impingement ...
