Finite Difference Analysis of Plane Couette Flow using MATLAB
Abstract: AbstractInternal flow is a flow for which the fluid is confined by a surface. Hence, the boundary layer is unable to develop without eventually being constrained. An internal flow is constrained by the bounding walls, and the viscous effects will grow and meet and permeate the entire flow. Some examples of internal flows are flow between two parallel horizontal plates, Couette flow, plane poiseuille flow, flow through pipes, etc. In …

BUCKLING ANALYSIS OF COMPOSITE CYLINDRICAL SHELL STRUCTURE USING FINITE ELEMENT ANALYSIS
Abstract: When designing cylindrical shells one should consider not only the strength problem in service, but also the buckling problem. Cylindrical shells such as thin-walled structures are susceptible to buckling when subjected to static and dynamic stresses. The vessels are exposed to dynamic sea conditions depending on their usage. The functional failure of a pressurized composite vessel or a composite pipe in the form of leakage or weeping of the contained …

Preparation and Characterization of Composites Based on Polylactide and Herbs with Anti-Bacterial Properties
Abstract: Poly (lactic acid) is a polymer with increased interest in manufacturing a containers for different kinds of food. But the food stored in those containers comes with certain amount of bacteria and/ or molds. This suggest that the food can have shorter shelf life. That why is needed a container in which the food can maintain for longer period. In this paper were studied the properties of composite materials based …

Study of Physical and Chemical Properties of Heavy Waxy Crude Oil from Cambay Basin Using Rheometer and Cross-Polar Microscope
Abstract: Production of heavy crude is quite difficult as the pressure drops from reservoir to production facility are quite large. This often leads to the precipitation and deposition of common organic solids (paraffin). These solids may deposit on surfaces, collect in low-energy regions or increase the effective viscosity of the flowing fluid. The net effect is an increase in pressure drop for a given rate through reduction in flowing area or …

Enhanced Oil Recovery (EOR) Process through Miscible Gas Injection: A Case Study of an Iranian Oil Reservoir
Abstract: Speedy computers and development in equations’ numerical solutions have enhanced applying simulation to predict the behavior of oil and gas reservoirs. The pressure in hydrocarbon reservoirs reduces overtime due to utilization of oil and gas resources until the fluid pressure itself is no more able to transfer it to the surface, and even if it reaches to the surface, its production is not cost-effective. Whereas, large amounts of hydrocarbon resources …

Wax Deposition Profile Estimation in Production Pipeline Review
Abstract: Wax deposition has been a major challenge in flow assurance of paraffinic crude oils. A major problem occurs because of a decrease in the bulk oil flowing and pipe wall temperatures. Wax deposits form when the temperature of the produced fluid falls below the wax appearance temperature or the cloud point temperature. Problems like pipeline plugging, increased pumping pressure and reduction in production rates are very common. Sophisticated mechanical and …
