In this work, experimental and modelling analyses are performed in order to improve the compression efficiency of a Liquid Piston Gas Compressor (LPGC), which utilizes column water for air compression. Due low cost easy manufacturing, aluminium parallel plates used as heat exchanger inside LPGC absorb thermal energy from compressed hence increase compressor. A comprehensive set numerical gain d...

Dual fuel combustion leverages a high-reactivity (HRF) to ignite premixed low reactivity (LRF)–air mixture achieve high efficiencies and engine-out emissions. The difference in the relative amounts of these fuels in-cylinder stratification profoundly impacts dual combustion. effect increasing LRF energy substitution on at various fixed HRF (diesel) quantities was experimentally studied for two ...

A randomized, controlled clinical trial was conducted to compare two different implant treatment modalities for edentulous patients with severely resorbed mandibles. In one modality (the IMZ group), two intramobile cylinder implants were placed, connected by a Dolder bar and provided with an overdenture, and in the other (the TMI group), a transmandibular implant with a triple bar and cantileve...

The Malliavin calculus is an extension of the classical calculus of variations from deterministic functions to stochastic processes. In this paper we aim to show in a practical and didactic way how to calculate the Malliavin derivative, the derivative of the expectation of a quantity of interest of a model with respect to its underlying stochastic parameters, for four problems found in mechanic...

Due to environmental changes across the global, there is urgent need take care of pollutions. 15–20% air pollution caused by automobiles, reason behind incomplete combustion, lack oxygen in fuel and etc. There are so many methods developed make good combustion inside cylinder adding additives, using biodiesels, changing injection timing pressures. Present researchers Nano additives harmful plan...

Forced mobilization apparatus and macroscopic analysis of joint degradation. (a) Following sham (control) or OA surgery, FM animals underwent forced mobilization. Animals walked on a rotating cylinder for 30 min, three times per week. (b) FM forces the maximal extension and flexion of the knee joint (white arrow). To assess macroscopic changes to the articular surface, knee joints were dissecte...

In this study; metanol-diesel fuel, organometal MnO2 fuels were used to improve the properties of diesel fuel. Besides, the effect of methanol fuel on engine oil was also examined experimentally in a four cylinder, direct injection diesel engine running at 200 bar. Three different diesel fuels were prepared by adding 5, 10 and 15% methanol into diesel fuel. In order to prevent phase separation ...

Hydraulic integrated interconnected regenerative suspension (HIIRS) is a novel system that can simultaneously harvest the vibration energy in and enhance vehicle dynamics. The parameter sensitivity of HIIRS analyzed significant parameters are optimized this paper. Specifically, half-vehicle model with established. Based on model, hydraulic three objectives, ride comfort, road holding, average h...

an experimental study was carried out on the wake of a cylinder on the back of which a plate is installed parallel to the fluid flow, with different terminal angles, where the reynolds number is 50000. at the end of the plate, blades with the height of 0.25 equal to the cylinder diameter and with 45, 90 and 135 degrees angle from the horizon, are installed where the cylinder diameter is equal t...

Abstract Ansys software is used to simulate the welding process of boring bar new cylinder head machine. The indirect coupling method analyze temperature field, then stress field and deformation. It found that for double support structure, highest occurs at outer stiffened plate small diameter end, lowest both ends inner structure. deformation whole structure mainly comes from axial deformation...
