One of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. Several parameters should be optimized in a fluid injection process. The usual optimizing methods evaluate several scenarios to find the best solution. Since it is required to run the reservoir simulator hundreds of times, the process...

designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied together with design and build a low-speed wind tunnel. a specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. there are generally three regi...

Microscopic oil displacement of water flooding and sweep efficiency of continuous gas injection could be improved by water alternating gas (WAG) injection. The WAG injection process aims to squeeze more oil out of the reservoirs; in this method, water and gas are alternatively injected into the reservoir. Also, availability of hydrocarbon or CO2 gases in the field makes it attractive for gas-ba...

This paper is devoted to the modelling of a Diesel Common Rail Injection System. The objective is twofold : to build a simulator which will be used later for the rail pressure control scheme validation, and to get linearized models for control design. A mathematical model, based on physical equations is developed and used as a simulator. Then time responses of the rail pressure of a real engine...

in our country, student transportations’ security and driving accidents statistics for students is one of the major concerns for relevant organizations such as educational organization. in current year, a system, was named sepand, was formed in city taxi driver :::::::union::::::: by educational organization, naja traffic and city taxi driver :::::::union:::::::. in this systems’ plan, basis on...

in this research the experimental and theoretical studies on different enhanced oil recovery (eor) techniques, i.e. water flooding (wf), gas injection (gi) and water alternating gas process (wag) were performed on specimens taken from an iranian carbonate offshore reservoir at the reservoir condition. the experimental results for each specified techniques were compared with the corresponding re...

In nuclear power plants (NPPs), digital I&C systems are expected to lead to increasing level of safety and improved performance in communication, maintenance, and signal processing. They are expected to be used in all new NPP designs, while existing NPPs are being evaluated for the switch from analog to digital control systems. Switching from analog to digital or working with hybrid systems has...

Evaluating embedded systems vulnerability to faults injection attacks has gained importance in recent years due to the rising threats they bring to chips security. The task is particularly important for micro-controllers since they have lower resistance to fault attacks compared to hardware-based cryptosystems. This paper reviews recent embedded fault injection simulators from literature and pr...
