摘要: The objective of the present study is to investigate hydraulic characteristics and single-phase thermal behaviour a capillary tube with internal diameter 130 w m. As Reynolds number varies in range from 100 up 8,000 experiments, flow regimes laminar turbulent are thoroughly investigated. laminar-to-turbulent transition studied depth. Experiments show that occurs for 1,880-2,480, while heat transfer correlations regimes, developed conventional tubes, not adequate calculation coefficient microtubes.
