Application of CO2-Switchable Oleic-Acid-Based Surfactant for Reducing Viscosity of Heavy Oil
Molecules, 2021 CO2-switchable oligomeric surfactants have good viscosity-reducing properties; however, the complex synthesis of surfactants limits their application. In this study, a CO2-switchable “pseudo”-tetrameric surfactant oleic acid (OA)/cyclic polyamine (cyclen)

Heat Transfer and Flow of a Gel Fuel in Corrugated Channels
Energies, 2022 For propulsion systems using gel fuels, reducing the gel fuel viscosity is essential for achieving better atomization and combustion. In this paper, we investigate the flow and heat transfer in a water-gel with a temperature and shear dependent viscosity.

Experimental Study on Aging Oil Viscosity Reduction Caused by Ultrasound
Journal of Harbin University of Science and Technology, 2019 Aging oil usually performs large viscosity and poor liquidity，which make it difficult to transport effectively. In this paper, the aging oil is treated by ultrasonic wave, and the viscosity reduction effect is evaluated by measuring the viscosity curve ...

Current Status and Future Trends of In Situ Catalytic Upgrading of Extra Heavy Oil
Energies, 2023 In situ catalytic upgrading of heavy oil decomposes viscous heavy oil underground through a series of complex chemical and physical reactions with the aid of an injected catalyst, and permits the resulting lighter components to flow to the producer under

Thromboembolic Prophylaxis and Viscosity Reduction with Ancrod [PDF]
Thrombosis and Haemostasis, 1977 Blood and plasma viscosity were measured at high shear rates in 10 patients receiving intravenous ancrod and 9 patients receiving subcutaneous ancrod. In both groups significant viscosity reduction accompanied fibrinogen depletion and there was no significant fall in haematocrit. Blood and plasma viscosity were also significantly reduced in 28 patients
