Sigma heat transfer

WebFeb 2, 2011 · In heat transfer, as the fluid flows along the tube, the wall layers are heated or cooled. In this case, at the entrance region of the tube, the fluid core retains a temperature equal to that at the inlet T 0 and does not participate in heat transfer. Temperature variation occurs in the wall layers. Thus, near the tube surface in the entrance ...
