Ultra-High Pressure Modeling and Experiments Review
The RDHWT/MARIAH II energy addition, run time, and mass flow rate requirement simply large air and nitrogen fluid volumes at the highest practicable static enthalpy. The objective of the gas supply concept development is the satisfaction of ultra-high pressure (UHP), high temperature thermodynamic requirements in a facility with acceptable safety and economic risks. The primary challenges for the mechanical design are connecting multiple volumes at pressures greater than 1,400MPa and temperatures greater than 500 K; fabricating high strength steel sections approximately 2 m in typical dimension, and reacting the pressure-related forces in the system. In the 'octahedral module' concept, four UHP intensifiers and two UHP manifolds are arranged in an 'octahedral' geometry that results in acceptable deviatoric stresses at cross bores. Multiple modules join to provide the required UHP volume at a stagnation pressure of 2100MPa and stagnation temperature of 750 K.
