Abstract: Built upon the acoustic impedance of circular apertures and cylindrical cavities as well as the principle of electroacoustic analogy, an impedance model is developed to investigate theoretically the sound absorption ...

Abstract: Under quasistatic uniaxial compression, inserting aluminum foams into the interstices of a metallic sandwich panel with corrugated core increased significantly both its peak crushing strength and energy absorption per unit ...

Abstract: A numerical investigation was carried out to characterize the thermal performance of finned metal foam heat sinks subject to an impinging air flow. The main objective of the study was to quantify the effects of all relevant ...

Abstract: This study reports on heat transfer characteristics on a curved surface subject to an inclined circular impinging jet whose impinging angle varies from a normal position خ¸â€‰= 0 deg to خ¸â€‰= 45 deg at a fixed jet ...

Abstract: We introduce a new class of ventilated brake disk which incorporates an open cellular core: wirewoven bulk diamond (WBD). Transient and steadystate thermofluidic characteristics are presented. As reference, a commercially ...

Abstract: This study presents impingement cooling from a flat plate by multiple asymmetric jets. Such jets are discharged through blunt-edge inline orifice holes with a thickness-to-diameter ratio of t/Dj = 0.5 and a jet-to-jet ...
