Full Coupling of Flow, Thermal and Mechanical Effects in COMSOL Multiphysics® for Simulation of Enhanced Geothermal Reservoirs

D. Sijacic[1], P. Fokker[1]
[1]TNO, Utrecht, The Netherlands

The effective modeling of enhanced geothermal systems (EGS) requires the coupling of geomechanics, fluid flow and thermal processes. An understanding of the complete system with these coupled processes is vital, not just for reservoir stimulation targeted at enhancing reservoir performance, but also for the understanding, prediction and prevention of induced seismicity. Thermal effects however ...

FEA Mechanical Modeling of Torque Transfer Components for Fully Superconducting Rotating Machines

[1]University of Houston, Houston, TX, USA

NASA is funding the development of a high-fidelity fully superconducting machine sizing tool able to generate optimized designs based on thrust requirements and design constraints. Several mechanical challenges need to be overcome during the design of the torque transfer components. Reducing the conducted heat load requires the use of different materials in the torque path, which requires ...

Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that stresses generated do not exceed the endurance strength of the material. In this paper, structural mechanics ...

[2] CEA DAM, Valduc, Is-sur-Tille, France

In order to predict the residual mechanical state of assemblies during pulsed laser welding, mechanical and metallurgical behaviors of materials need to be precisely characterized. Based on experimental data and analyses [1], a numerical model is developed in COMSOL Multiphysics® software to take into account the predominant effects identified for TA6V. First of all, the metallurgic behavior ...

MEMS Based Silicon Load Cell for Weighing Applications

Thermal Stresses in Functionally Graded Metal-Ceramic Plates

E. Gutierrez-Miravete [1],
[1] Rensselaer at Hartford, Hartford, CT, USA

Functionally graded composite materials are attracting interest among design engineers since structural component properties can be designed and customized into finished parts through processing. The controlled variable is the concentration of reinforcing particles at various points within the component. While locally isotropic, part properties can be made to vary in a controlled manner from ...
