| The main objective of the project will be to study various effects and potential uses of winds in Mars. In particular, the project will focus principally on thermally-driven winds, such as mountain-valley winds and slope winds, in Mars. Thermally-driven winds are very common in Mars over sloping regions. These winds may reach significantly high speeds for steep slopes, and govern near-surface winds in many Martian sites. Thermally-driven winds develop due to natural convection in the Martian Planetary boundary layer (PBL) driven by temperature gradients between the surface topography and the atmosphere. Earth's atmospheric boundary layer (ABL) modeling approaches are being applied also to study the Martian PBL, including Reynolds-averaged Navier Stokes (RANS) k'' turbulence models, as well as very high-resolution large-eddy simulations (LES). Numerical simulations on Earth usually with commercial computational fluid dynamics (CFD) codes. This work might explore the use of OpenFOAM open-source CFD code for simulating slope flows on Mars.
The objectives of the project will be to analyze: 1) the potential of these winds for generation of wind energy in Mars, 2) the suitability of these winds to blow-off dust from solar panels, 3) the aerodynamic loads imposed on Martian domes and structures of long-term human settlements, and finally 4) candidate landing sites for Mars missions, etc. Namely, we will study the influence of the following parameters on the potential wind energy production: the width of valley, mountain slopes, surface roughness, etc. The numerical model results will be compared to experimental results from previous investigations. The procedure and methodology will be as follows: 1. Literature search and review of relevant bibliography 2. Formation on appropriate software packages and codes (e.g., SolidWorks and OpenFOAM or ANSYS Fluent) 3. CFD analysis of the fluid problem: a. Design of CAD geometries (e.g., SolidWorks) b. Meshing of the fluid problem c. Solving the problem with suitable solver (e.g., OpenFOAM or ANSYS Fluent) d. Post-processing of the CFD results 4. Comparison of the numerical results with results from experiments reported in the literature 5. Development of wind energy density maps in relevant locations 6. Draw conclusions from the study 7. Write thesis and prepare final presentation |
