Simulation Results and Experimental Validation of SOFC Operation Under Hydrogen

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Thermal simulation of two-phase flow in under-balanced drilling operation with oil and gas production

The accurate prediction of wellbore temperature distribution helps to accurately estimate well pressure profile and bottom-hole pressure (BHP) which is important in the under-balanced drilling (UBD) operation. In this paper effect of temperature variation due to heat transfer of drilling fluid with the formation and also oil and gas production from the reservoir into the annulus in under-balanc...

Numerical Verification and Experimental Validation of Sliding Mode Control Design for Uncertain Thermal SOFC Models

The design of reliable and robust control strategies for the automatized operation of SOFC systems in a decentralized power grid demands for the use of nonlinear dynamic system models with a large number of physical parameters. These models have to cover the most dominant nonlinear effects and include knowledge about the uncertainty of specific parameters. In this paper, interval variables are ...

Numerical simulation of in-cylinder tumble flow field measurements and comparison to experimental results

This paper presents a comparison between measured and predicted results of the in-cylinder tumble flow and the flow coefficient generated by a port-valve-liner assembly on a steady-flow test bench. In this study, computational fluid dynamics (CFD) methods were employed to gain further insight into characteristics of an engine. The purpose was to advance understanding of the stationary turbulenc...
