Three examples are selected as representative cases concerning the basic convective heat transfer in the heat exchanger field, each of which has a specified parameter for optimizing the individual specific condition. First, the chemical vapor deposition of a silicone layer for SiH4 on the hot bottom wall of a horizontal rectangular furnace duct is discussed, assuming that a spatially uniform thickness of the layer is the optimal one. Second, the compact heat exchanger is studied with the insertion of a twisted strip in each channel so that the outlet temperature of the heated gas becomes uniform by changing the twist pitch appropriate to each channel. Third, a shell and helical tube heat exchanger is discussed for controlling flow-induced tube vibration by inserting separating plates between the tube arrays and optimizing the interval of the plates.
