SIMULATION OF UNSTEADY STATE FLOW OF NATURAL GAS IN PIPELINES USING FINITE VOLUME METHOD IN 2D CYLINDRICAL Coordinates

ABSTRACT              Transient compressible natural gas flow through a pipeline was studied by the use of a finite volume method in 2D axisymmetric cylindrical coordinates. To account for turbulence within the pipeline system, the standard turbulence model was simulated together with the Navier Stokes System of equations via the Reynolds-Averaged method. The equation of state employed was the SoaveRedlich-Kwong equation. Implicit discretization was used...

THE IMPACT OF MALARIA ON LIPIDS AND GLUCOCORTICOIDS IN CHILDREN UNDER TEN YEARS AT THE KORLE BU TEACHING HOSPITAL

ABSTRACTBackground: Malaria is a common and life-threatening disease in Ghana. Malaria infection has been implicated in lipid and glucocorticoid imbalances among children. Cortisol-induced stresses and parasitaemia may affect brain development and risk of cardiovascular disorders among children.Aim: To investigate the impact malaria has on lipids and glucocorticoids in children..Method: A comparative cross-sectional study using random sampling method was used in this study conducted between t...

Biofuel Production Potential of Anacardium Occidentale (Cashew)

ABSTRACTMature and ripe cashew fruits were harvested, washed and the apples separated from the nuts. The apples were crushed and the juice extracted, sieved and treated with potassium metabisulphite, to check the activities of undesireable microorganisms, before fermentation. A 3-spatula full of true wine yeast, Saccharomyces cerevisiae var. ellipsoideus, was rehydrated and inoculated into a 2.5-liter part of the juice and allowed for 5 days in a room temperature of 32.50C to ferment. A...

VAPOR–LIQUID EQUILIBRIA OF MIXTURES CONTAINING n-DECANE, CARBON DIOXIDE AND ARGON USING MOLECULAR SIMULATION TECHNIQUES (GIBBS ENSEMBLE MONTE CARLO SIMULATION)

 Abstract The CO2–hydrocarbons systems is common in oil and gas industry as a geological fluid. CO2 plays a vital role in biological processes namely photosynthesis, respiration, and actively participates in the carbon cycle. However, the time gradient of carbon dioxide concentration in the atmosphere has become a major global concern. The environmental challenges associated with the control and management of anthropogenic emissions of greenhouse gases have been the focal po...

EFFECT OF LYE SOURCE ON THE KINETICS AND QUALITY OF LOCAL SOAP

This research presents the effect of lye on the kinetics and quality of local soaps. To achieve this, 40ml of 10 percent lye (palm bunch, coconut shell and synthetic sodium hydroxide) reacted with 60ml of oil (palm oil and palm kernel oil) in a batch system, under conditions as, constant temperature (50 degree celcius) and constant stirring (100 rpm). Variation in saponification value and free fatty acid was monitored with time, that is, at intervals of 2mins. It was noticed that a...
