Postdoc M/F : High-Performance Computing for multi-physics simulations of solar receivers with fluidized beds

In solar receivers, solar radiation is concentrated on vertical tubes containing a gas-particle mixture, with the goal of heating particles to ~1000°C. However, current Euler-Euler (Two-Fluid Model, TFM) simulations fail to accurately predict wall-to-bed heat transfer coefficients, with discrepancies of up to a factor of 2 compared to experiments (e.g., 1200 W/(m²·K) vs. 600 W/(m²·K)).
