  • An investigation was conducted to study the pressure loss characteristics of a highly viscous fluid flow across a sudden contraction. The objective of this work was to have a better understanding about the fluid flow phenomena across a narrow slot, which resembles the produced oil flow through the slotted liner during the SAGD operation. An extensive experimental work was undertaken along with the theoretical modelling for this research work. The pressure loss, the flow rate and the fluid viscosity were measured for different geometrical configuration of slots using an experimental setup. For a sudden contraction; slot width, aspect ratio, thickness to diameter ratio, diameter ratio and slot shape were varied over an appropriate range to encompass their effects on the pressure loss. The viscosity of the fluid was varied by varying the temperature within the range of 50 °C ≤T≤ 75 °C. The Pressure loss was normalized using kinetic energy and characteristics were observed for the operating range of Reynolds number (Re≤ 30). The results show that for this low region of Reynolds number, the pressure loss decreases with increasing Reynolds number. The theoretical model also predicts the same trend of pressure loss. Within the operating range of viscosity (40 cP <μ< 300 cP) the results show that the pressure loss decreases with decreasing viscosity. The Aspect ratio was varied within the range of 1 – 100 and general trend shows an increase in pressure loss with increasing aspect ratio. The Diameter ratio was another dominant factor for pressure loss across the sudden contraction. The results represent that pressure loss will increase with decreasing diameter ratio.
