Abstract: A variety of methods for the prediction of acoustic resonances in heat exchangers are recommended in the literature. There is currently no clear guideline available to designers for the avoidance ...

Abstract: Experiments have been performed in a low turbulence wind tunnel to investigate the effect of tube pitch to diameter ratios, depth of bank, and Reynolds number on the parameters associated with ...

Abstract: The measurement and correct modelling of damping is of crucial importance in the prediction of the dynamical performance of systems for a wide range of engineering applications. In most cases, ...

Abstract: Most previous studies of boundary lubrication have ignored the contribution of surface roughness to friction. However, recent work by Moalic et al. (1987) has shown that when asperity contacts ...

Abstract: A brief summary of the methods commonly used for the analysis of rough surfaces and the errors associated with these techniques is given. A frequency domain digital differentiator is shown to ...

Abstract: The prediction of tube or acoustic resonance due to cross-flow in heat exchangers is dependent upon knowledge of the flow characteristics for a given tube array geometry. For this, a Strouhal ...
