Numerical Investigations of the Influence of the Spool Structure on the Flow and Damage Characteristics of Control Valves

Fluids
This study investigates the flow dynamics and damage characteristics of liquid level control valves in direct coal liquefaction processes. The primary failure mechanisms are identified as eccentric jet-induced unilateral wall damage, cavitation erosion ...

Advanced progress concepts for direct coal liquefaction

, 1995
Given the low cost of petroleum crude, direct coal liquefaction is still not an economically viable process. The DOE objectives are to further reduce the cost of coal liquefaction to a more competitive level.
