# Industrial Specification: Overflow Vortex Finder

## 1. Technical Definition
A critical component of a Continuous Starch Hydrocyclone Separator that detects and directs the overflow stream containing fine starch particles.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-0.5 bar differential pressure, 0.5-2.0 m/s tangential inlet velocity, 60-80°C fluid temperature**. Failure boundary: **0.8 bar differential pressure (vortex collapse), 2.5 m/s tangential velocity (boundary layer separation), 85°C fluid temperature (polymer degradation)**, Mechanism: **Vortex breakdown due to excessive pressure differential exceeding Taylor-Couette stability limit, boundary layer separation at Reynolds number &gt; 5000 causing flow detachment, thermal degradation of starch polymers above glass transition temperature**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
