Learn to validate mesh quality, select solvers, and prevent simulation failures. Based on 10+ years of ANSYS expertise.
What you’ll learn
– Predict mesh skewness failures before simulations using aspect ratio physics
– Decode periodic error traps in turbines/compressors with boundary theory
– Master wall function trade-offs: accuracy vs. stability in rotating machines
– Spot turbulence model mismatches causing 30% efficiency drops in pumps
– Reverse-engineer CFD garbage outputs using continuity/momentum forensics
– Defend against vortex shedding chaos in blade rows with Strouhal theory
– Solve transient rotor-stator errors with time-scale physics (no solver needed)
– Detect false convergence from poor residuals/scaling in 3 steps
– Validate simulations mentally using dimensionless numbers (Re, Ma, y+)
– Build bulletproof meshes by controlling expansion ratios & cell quality

Requirements
– Basic physics curiosity (e.g., "Why does fluid speed up in narrow gaps? etc")
– Patience to master CFD error-forensics
– High-school physics (pressure/forces)
– STEM background (engineers/students/hobbyists)

Description
Why do industrial turbomachinery simulations often mislead engineers?Overlooking foundational theoretical principles – like1mm mesh gaps causing 200% pressure errors(Module 1),y+ mismatch invalidating turbulence models(Module 2), orsolver misapplication corrupting rotor dynamics(Module 3) – results in costly prototype failures. This course deliversapplied theory to intercept simulation errors before hardware commitment.
You will learn to:

Diagnose mesh-induced errors(gaps, skewness) usingcontinuity and momentum principles- exposing why a 1mm gap invalidates results (Module 1).

Select turbomachinery-specific y+ ranges and wall functionsto achieve ±5% validation against experimental data – avoiding common turbulence modeling pitfalls (Module 2).

Contrast ANSYS Fluent vs. CFX solver architecturesfor rotating machinery applications – predicting stability issues in compressors or turbines through algorithmic differences (Module 3).

Prevent vortex shedding failures with Strouhal theoryand detect false convergence in residuals using a 3-step framework – securing transient simulations (Module 4).

Equip yourself with system-agnostic expertise – enroll to safeguard your turbomachinery projects from theoretical oversights.

Who this course is for:
– This course is designed for CFD auditors, engineering managers, and hardware leads who need to sniff out simulation risks before they become costly prototype failures.
– Bring a critical eye for technical reports and basic physics literacy (e.g., understanding pressure drives flow). No prior CFD experience is required – we focus purely on forensic skills, not software operation.
– What You’ll Gain Decode "garbage inputs" hidden in vendor CFD reports. Judge simulation credibility using mesh/y+/turbulence red flags. Spot $500k risks from skewed results before committing to hardware. Ask vendor-crushing questions like "How did you validate wall functions?" or "Show your gap closure strategy!"
