Presentation of Novel Tube to Enhance Crude Oil Fouling in Heat Exchangers

The objective of the research is to represent a novel arrangement of plain tube for heat transfer coefficient enhancement. Experiments handled in stainless steel_316 tubewithout roughness and hot crude oil is circulated in constant heat flux condition in the related set up. Pressure drop is measured in this set up andcompared with pressure drop in a smooth tube with the same operating conditions. Heat transfer coefficient is one of essentialparameter for design of heat transfer equipments and in this experimental work this is investigated for an Iranian crude oil in the plain tube. Heattransfer coefficient in plain tube is higher than other commercial enhanced tubes. Plain tube improves the performance of heat transferequipments and also optimizes the size of the mentioned devices. Consequently this type is advantageous in Energy and cost saving.
