Problems solved by technology

The upper part of the rod bundle channel is equipped with a thermocouple carrier. This device can realize real-time and accurate measurement of the temperature field in the rod bundle channel. However, this method can only collect the temperature field information of the fluid in the rod bundle channel, and cannot effectively measure the flow heat transfer. characteristics for analysis
Therefore, it is difficult to extend the device and method to the experimental study of flow transfer characteristics in multi-rectangular channels of plate-shaped fuel elements with uniform heat release.
