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. ...

Effects of Blast Vibration on Unplanned Dilution in an Underground Metal Mine

One of the factors affecting overbreak or slough of the roof and walls of underground stopes, causing unplanned dilution is blast vibration. The amount of damage caused by earth vibration can be measured in terms of peak particle velocity (PPV). In this study, in order to investigate the effects of blast vibration on the occurrence of unplanned dilution, 72 three-component records acquired upon...

A Complementary Numerical and Physical Investigation of Vortex-induced Vibration

Results are presented from low Reynolds number experimental investigations of vortex-induced vibration and comparison is made with results from corresponding twoand three-dimensional direct numerical simulations. It is shown that three-dimensional simulations are required to reproduce the response envelope observed experimentally. Phase-averaged contours of spanwise vorticity demonstrate the pr...

BLAST++: BLASTing queries in batches

UNLABELLED BLAST++ is a tool that is integrated with NCBI BLAST, allowing multiple, say K, queries to be searched against a database concurrently. The results obtained by BLAST++ are identical to that obtained by executing BLAST on each of the K queries, but BLAST++ completes the processing in a much shorter time.
