水平単列円管の自然対流熱伝達

抄録

Experiments of natural convection heat transfer from central cylinder in a single horizontal array to air were carried out using copper cylinders with d=50.8mm in diameter and 500mm in length. Five cylinders heated isothermally were placed parallel to each other with an equal distance. The spacing of the cylinder array was widely varied from p/d=1.01 to 1.75, where p is the cylinder-to-cylinder pitch. Local and average heat transfer from the central cylinder in the array were measured by means of Schlieren optical and calorimetric methods, respectively.
