# Industrial Specification: Water-Cooled Crucible

## 1. Technical Definition
A crucible with integrated water cooling channels designed to contain and process high-temperature materials while maintaining controlled temperature through active cooling.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-15 MPa internal pressure, 5-95°C coolant temperature, 800-1800°C material temperature**. Failure boundary: **Coolant boiling point at operating pressure (e.g., 120°C at 0.2 MPa), thermal stress exceeding yield strength of crucible material (e.g., 250 MPa for copper alloy), flow velocity exceeding 3 m/s causing erosion**, Mechanism: **Phase change heat transfer limitation (coolant boiling creates insulating vapor layer), differential thermal expansion between crucible wall and cooling channels exceeding material elastic limit, turbulent flow-induced cavitation erosion at channel surfaces**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.
