Abstract Asmari formation is one of most important reservoirs in southwest of Iran. Production from this reservoir is mostly due to presence of fracture systems especially in Marun oilfield, hence characterization of fracture zones in reservoir facilitate the specification of perforation zones, analyzing the performance of local faults and fracture […]

Abstract:   Drilling process is the most important part of exploitation of hydrocarbon reservoirs and accomplishment of drilling a well is determined by proper choice of the drilling fluid. The drilling fluid is related either directly or indirectly to almost every drilling problem. Improvement of drilling fluid properties therefore would have […]

Abstract: Separation and reattachment of air flow through a sudden expansion in an annular passage with uniform heat after step are considered in this paper. The annular passage with step is applied in the design of many heat related applications where heat transfer is concerned. In this work, numerical simulation […]

Abstract: The Stirling engine is an external combustion engine that works with any heat source. Surrounded by heating with gas pressure to the piston displacement and cooling gas, the piston reaches the initial point. This paper explores the Laminar flow modeling for analysis and the results of its Laminar flow […]
