Analysis of effectiveness of heat exchanger shell and tube type one shell two tube pass as cooling oil

Abstract Heat exchanger is a device that produces heat transfer from a fluid to another fluid, which can be applied as a cooling oil to maintain the oil temperature at the operating standard. This study was conducted to determine whether the oil temperature exit the shell and tube heat exchanger one shell and two tube pass, by calculating the effectiveness of the cooling oil on the tube (tube) using water as cooling fluid flowing through the shell (shell) using NTU-ε and experimental studies. Shell and tube heat exchanger one shell and two tubes pass effective used to cooling oil, because it can reduce oil temperature up to 32 %.
