The influence of installation conditions of heat meters on interior fluid field and flux mearsurement accuracy

The installation condition of heat meters has an influence on interior fluid field and flux measurement accuracy. In this paper, this influence is investigated through experimental research and numerical simulation. The results indicate that the influence of the length of tubes in front of heat meters can be neglected when L≥4D (L is the length of tubes in front of heat meter, D is the diameter of heat meter). This conclusion has been of great value on academic theory and practical application.
