Conservation Laws for Coupled Hydro-mechanical Processes in Unsaturated Porous Media: Theory and Implementation

Description: We develop conservation laws for coupled hydro-mechanical processes in unsaturated porous media using three-phase continuum mixture theory. From the first law of thermodynamics, we identify energy-conjugate variables for constitutive modeling at macroscopic scale. Energy conjugate expressions identified relate a certain measure of effective stress to the deformation of the solid matrix, the degree of saturation to the matrix suction, the pressure in each constituent phase to the corresponding i… more

Computational and Experimental Analysis of the Effectiveness of the Argon Reservoir

Description: Experimental and computational studies were performed to evaluate the effectiveness of an Argon Reservoir (AR). The AR is designed to prevent the ingress of air into the extraction furnace during the insertion and removal of the extraction basket, which contains Tritium Producing Burnable Absorber Rods. Computational computer code studies were performed to evaluate the AR design concept. Based on the results of this study it was concluded that the Argon reservoir would be very effective in keep… more

A Flow-Channel Analysis for the Mars Hopper

Description: The Mars Hopper is an exploratory vehicle designed to fly on Mars using carbon dioxide from the Martian atmosphere as a rocket propellant. The propellent gasses are thermally heated while traversing a radioisotope ther- mal rocket (RTR) engine’s core. This core is comprised of a radioisotope surrounded by a heat capacitive material interspersed with tubes for the propellant to travel through. These tubes, or flow channels, can be manu- factured in various cross-sectional shapes such as a specia… more

Acquisition of Crosswell Seismic Monitoring Data

Description: Crosswell seismic acquisition provides an ideal geometry for monitoring travel time changes in the subsurface. Analysis of delay time in terms of a characteristic frequency allows us to estimate optimal acquisition parameters (frequency and distance). We have deployed standard data acquisition equipment for continuous monitoring of crosswell travel time in two separate field experiments, with well spacing of 3 and 30 m. The acquisition hardware used for the field experiments is described, along… more
