The critical heat flux (CHF) condition is characterized by a sharp reduction of the local heat transfer coefficient as a result of the replacement of liquid by vapor adjacent to the heat transfer surface [1]. The CHF condition in flow boiling can be of different nature [1–5].

This paper discusses a new automated, computer controlled heat flux measurement facility. Continuous transient and steady-state surface heat flux values varying from about 0.3 to 6 MW/m2 over a temperature range of 100 to 1200 K can be obtained in the facility.

Soil heat flux is sometimes ignored because its magnitude is often small relative to the other terms in the energy balance equation. The daily and yearly sums are normally near zero, but daily values can be significant when the soil is heating in the spring or cooling in the fall.

Sensors and Actuators A: Physical, 1994
Abstract A method and sensor for direct temperature-gradient and heat-flux measurement is proposed. The semiconductor heat-flux sensor is based on the effect of thermodrift of charge carriers in a limited crystal. It represents a plane intrinsic semiconductor with different temperatures and different surface-recombination velocities at the opposite ...

The critical heat flux is the heat flux at which a transition from nucleate to film boiling occurs. It is of interest to designers because a marked reduction in heat transfer results from the transition, which may be rather sudden and which is accompanied by a substantial rise in surface temperature. Knowledge of the critical heat flux dictates whether
