“…The flow behavior of the investigated phenomenon and the obtained results are in agreement with the results from similar works in the field [17]. In [18], a similar CFD investigation is conducted but in terms of particle size it can only capture oil particles that are bigger than 100µm, whereas the method adopted for the current CFD analysis is more precise, as it allows the visualization of oil particles bigger than 10µm.…”

In this research paper, a numerical study regarding gas-oil separation is presented. Employing the geometry of a classic separator used by the NRDI for Gas Turbines COMOTI and a Computer-Aided Design (CAD) software, the computational domain was defined. To perform the Computational Fluid Dynamics (CFD) investigation, the mesh was created with the ANSYS Meshing tool, and the ANSYS CFX was employed as a solver. The computational domain was split into 5 subdomains, 3 were fluid and 2 were defined as porous media. The volume porosity, loss model, and permeability were set up. In terms of turbulence flow, the standard k–ε model was adopted. The results of the numerical calculations in terms of oil volume fraction and streamline profiles were used to analyze the separator configuration. The results show that the numerical investigation with the VOF (Volume of Fluid Method) - CFD model is capable of analyzing the performance of a two-phase separator equipped with two demisters-porous media.

The present work involves the development of helium based Pulsating heat pipe (PHP), which containing 48 parallel tubing parts. Pulsating heat pipe (PHP) is considered as one of the best alternatives for conducting metals and it is used for long distance heat transfer process. Their heat transfer capability and efficient thermal conductivity are the prominent properties which considered for applications. The region of the condenser was thermally sealed to the giffored mcmohanon cryo-cooler [gm-cryo cooler] using a cooling cap of 1.49 W at 4.2 K while 1.1 W of heat are allowed to the evaporator section at a filling rate of 70%, through comparing the 48-turn PHP and 8-turn PHP, a most intense efficient thermal conductivity of 12329 W/ mK was achieved in the 48 turn PHP. The influence of no turns of warm movement execution was observed with the same operating parameters and topographical parameters. Observations revealed that the temperature variations of PHP 48-turn was significantly less than that of PHP 8-turn. It exhibited efficient thermal conductivity, high capacity heat transfer and a good dry-out temperature response. Thus PHP 48-turn of series and parallel configurations are defined as excellent system designs and are accessible to the PHP cryogenics framework architecture.

In current trends the wood pellets are very significance role in the replacing of boiler fuel; it is a surrogate and renewable fuel. For this study comparative analysis of the fuel performance in the boiler is carried out effectively. Two categorize of fuel like as raw wood pellets and wood pellets are immersed in the bio- ethanol are taken to this experimental work. The thermal characteristics and thermal efficiency of the boiler with influence of two types of fuels are conducted efficiently. Normally the wood pellets having small pores it is used to absorb the bio ethanol while in immersion. Amid in the two fuels, wood pellets immersed in the bio ethanol are provided and increase the thermal properties as well as thermal efficiency compared to raw pellets. The flue gas constituent?s percentage such as carbon monoxide, oxygen, carbon monoxide and nitrogen oxides are analyzed, additionally the high temperature of flue gas also measured in the outlet of the chimney. No alteration is made in the boiler setup which is comfortable to both fuels.
