FCC Riser Fluid Dynamics Simulation

I need an expert in Ansys Fluent to simulate the fluid dynamics of a Fluid Catalytic Cracking (FCC) riser. The focus is on multi-phase gas-solid flow.

Key Requirements:
- Simulate gas-solid interactions
- Analyze and visualize flow patterns
- Provide detailed reports of findings

Ideal Skills and Experience:
- Proficiency in Ansys Fluent
- Strong background in fluid dynamics
- Experience with FCC processes and multi-phase flow

Please include previous relevant work and approach.
