Critical Heat Flux Apparatus
Product Code : EL-HTL-11090
The Critical Heat Flux Apparatus from Lab Exports demonstrates the different regimes of pool boiling by heating a thin test wire submerged in water and observing the transition from nucleate to film boiling up to the burnout point.
Specifications
| Test Wire | 35 gauge or 40 gauge, 10 cm length |
| Heater | Nichrome, 1 kW capacity |
| Trough | Glass, sufficient capacity to submerge the test wire |
| Observation | Table light to observe the test wire during boiling |
| Measurement | Voltmeter and ammeter for test wire input |
| Control | Dimmerstat to adjust voltage to the test wire |
| Services Required | 220V, 15A stabilised single-phase supply; floor surface 1m x 1m at working height |
Key Features
- Demonstrates the full range of pool boiling regimes up to the burnout (critical heat flux) point
- Test wire heated directly by passing current through it, submerged in constant-temperature water
- Glass trough allows clear visual observation of boiling behaviour, aided by a table light
- Dimmerstat control allows gradual increase of heat flux to observe regime transitions
- Voltmeter and ammeter directly measure electrical input to the test wire
- Interchangeable wire gauges (35 or 40) for comparative testing
Applications
The Critical Heat Flux Apparatus is used in heat transfer laboratories to study pool boiling heat transfer, helping students observe the progression from natural convection through nucleate boiling to film boiling and identify the critical heat flux (burnout) point.

Frequently Asked Questions
Q1. What does the Critical Heat Flux Apparatus demonstrate?
It demonstrates the regimes of pool boiling on a heated test wire, from nucleate boiling through to the burnout (critical heat flux) point.
Q2. What test wire is used?
A 35 or 40 gauge test wire, 10 cm long, is heated directly by passing current through it.
Q3. How is heat flux controlled?
A dimmerstat adjusts the voltage supplied to the test wire, allowing gradual increase of heat flux.
Q4. How is the test wire observed?
The wire is submerged in a glass trough of water and observed under a table light as boiling regimes develop.
Q5. What utilities are required to operate the apparatus?
It requires a 220V, 15A stabilised single-phase supply and a floor surface of approximately 1m x 1m.
