TL;DR: In this article, the effect of jet-to-plate spacing and Reynolds number on the local heat transfer distribution to normally impinging submerged circular air jet on a smooth and flat surface was investigated.

TL;DR: In this paper, the effects of the shape of the nozzle, jet-to-plate spacing and Reynolds number on the local heat transfer distribution to normally impinging submerged air jet on smooth and flat surface were investigated.

TL;DR: In this paper, an experimental investigation was carried out to study the heat transfer enhancement from a flat surface with axisymmetric detached rib-rougheners due to normal impingement of circular air jet.

TL;DR: In this article, the influence of jet-to-plate spacing (z/b) and Reynolds number on the fluid flow and heat transfer distribution was investigated on a smooth flat plate impinged by a normal slot jet.

TL;DR: In this article, the authors investigated the combustion characteristics of VCR engine using mixture of two biodiesel blend with diesel at 100% or rated load, at constant speed, and found that blends results in higher cylinder gas pressure, lesser heat release, higher rate of pressure rise and increased combustion duration.

TL;DR: In this paper, the impingement heat transfer characteristics of a synthetic jet are studied and the behavior of the average heat transfer coefficient of the impinged heated surface with variation in the axial distance between the jet and the heated surface is measured.

TL;DR: Phenomenological and physically-based constitutive models commonly used in machining simulations are presented and discussed and thermo-physical properties for thermal modelling of the machining process, and microstructure data for the chip and workpiece together with relevant experimental methods are discussed.

TL;DR: In this article, an experimental investigation was performed to study the heat transfer performance of a 36 nm-Al2O3-particle-water nanofluid in a confined and submerged impinging jet on a flat, horizontal and circular heated surface.

TL;DR: In this article, an experimental investigation at Reynolds number equal to 5000 on circular and chevron impinging jets by means of time-resolved tomographic particle image velocimetry (TR-TOMO PIV) and infrared (IR) thermography is performed at kilohertz repetition rate in a tailored water jet facility where a plate is placed at a distance of 4 diameters from the nozzle exit.

TL;DR: In this article, the effect of shape of the orifice of a synthetic jet assembly on impingement cooling of a heated surface is experimentally investigated, and the results showed that the heat transfer enhancement with a square orifice is larger than that with rectangular and circular shapes at larger axial distances for the same set of boundary conditions.
