It is interesting to analyze the effect of turbulent shear flow on pollution emitted by factory chimneys

⚡ Wind is NOT Steady - From RANS to LES ⚡ CFD-steady solutions deliver mean properties, such as mean velocity and mean pressure. Even though they have many eng. Wind pressures manifest high-frequency peaks that steady or low-resolution simulations cannot predict Experienced wind engineers use high-fidelity simulations - large eddy simulations (LES) - to compose wind loads for structural projects.

💡Comparison of wind pressure values between steady-state (RANS model) and transient (DDES model) wind simulation for a diagonal probe line in the Eiffel Tower, ✅Steady-state simulations provide insight into the average wind loads by assuming a constant flow condition as one time step, which is valuable for some engineering applications where wind conditions are relatively stable. On the other hand, transient simulations offer a time-dependent analysis that captures these fluctuating wind conditions, making it possible to predict the effects of wind load more realistic during a defined time domain, and it also leads to capturing critical wind pressure values (which may miss in steady-state simulation) in order to structural design, specifically in highly turbulent regions or suction areas. ℹSoftware: RWIND by Dlubal Software ℹMore info and free download model: https://lnkd.in/dvnjEqwz #DlubalSoftware #Eiffeltower #Windsimulation #Wind #CFD #RFEM #RWIND #terrain #StructuralEngineering #StructuralAnalysis

💡 Comparing Wind Pressure: Steady-State (RANS) vs. Transient (DDES) Wind Simulation for a Diagonal Probe Line on the Eiffel Tower ✅ Steady-State Simulations provide an average value of wind loads by assuming a constant wind flow over time, which is useful for scenarios where wind conditions remain relatively constant, offering a simpler, more predictable solution. However, Transient Simulations, using the DDES model, take into account time-dependent fluctuations in wind behavior. This approach provides a more accurate representation of wind loads during specific time intervals, capturing dynamic pressure changes that steady-state models may overlook. This becomes particularly crucial in regions of high turbulence or suction, where critical wind pressures can impact structural integrity and design. ℹSoftware: RWIND by Dlubal Software #WindSimulation #SteadyState #TransientSimulation #RANSModel #DDESModel #WindPressure #StructuralDesign #EiffelTower #Turbulence #SuctionAreas #CivilEngineering #CFD
