Measurement of temperature profiles in turbulent pipe flow of polymer and surfactant drag-reducing solutions
A device was built to measure temperature profiles of turbulent pipe flows of various drag-reducing fluids. It is easy to use and reliable. We measured temperature profiles over a range of conditions leading to accurate measurements down to y+ 10, for tests carried over Reynolds numbers Re between 10 000 and 90 000. The effects of high heat fluxes and buoyancy, in particular, were quantified to...
متن کاملPipeline Transportation of Liquid Manure
D to transportation costs, manures can be utilized for their fertilizer value only when the hauling distance is short. However, manure cannot be applied indefinitely to a limited land area close to the manure production site without creating problems of water pollution (Patni and Hore, 1978) and excessive nutrient and salt accumulation in the soil. Therefore, using manure for crop production on...
متن کاملPreparation and Application of Polymer Silicate Phosphate Ferric Sulfate Used in High-Viscosity Oil Refining Wastewater Treatment
A new kind of flocculants, named Polymer Silicate Phosphate Ferric Sulfate(PSPFS), was synthesized by ferrous sulfate used as the main material and activated silicic acid as additive. In this paper, High-Viscosity Oil Refining wastewater from Liaohe Petrochemical Corporation was the treatment object. Overall, the influencing factors and synthesis technology conditions of PSPFS were determined b...
متن کاملEffect of drag reducing polymer on air–water annular flow in an inclined pipe
Drag reduction (DR) for air and water flowing in an inclined 0.0127 m diameter pipe was investigated experimentally. The fluids had an annular configuration and the pipe is inclined upward. The injection of drag reducing polymer (DRP) solution produced drag reductions as high as 71% with concentration of 100 ppm in the pipeline. A maximum drag reduction that is accompanied (in most cases) by a ...
متن کاملNanomolar concentration of blood-soluble drag-reducing polymer inhibits experimental metastasis of human breast cancer cells
Metastasis is the leading cause of cancer mortality. Extravasation of cancer cells is a critical step of metastasis. We report a novel proof-of-concept study that investigated whether non-toxic blood-soluble chemical agents capable of rheological modification of the near-vessel-wall blood flow can reduce extravasation of tumor cells and subsequent development of metastasis. Using an experimenta...
