The classic example of a heat exchanger is found in an internal combustion … Modeling Study of Single-Well EGS Configurations. Heat transfers between these tubes together and with the shell side through tube walls. It is important to insulate the do-it-yourself heat exchanger shell so you don’t get a false exchange when your input air sucks heat from your room’s ambient through the exchanger exterior pipe wall. The velocity of the methanol flow through the tubes is 0.8 m/s (w). Here is an example of a 1-2 (1 shell pass and 2 tube passes) heat exchanger. This is known as a ‘one shell pass two tube pass’ type of shell and tube heat exchanger and consists of a U-tube bundle fitted into a fixed tube sheet.
