- Reduction of friction in fluid transport: experimental investigation G. Aguilar K. Gasljevic E.F. Matthys Física, Astronomía y Matemáticas polymer surfactant Drag reduction heat transfer reduction Drag reduction (DR) by the use of polymer and surfactant solutions is by far the most effective drag-reducing technique for turbulent flows (upto 8-fold reduction in friction coefficients is possible on straight pipes). From a fundamental point of view, the study of the DR phenomenonoffers an opportunity for a better understanding of turbulence in general; from a practical point of view, DR can be used to save pumpingpower. Commercial implementation of drag-reducing fluids has proved successful for oil pipeline transportation, and looks promising formany other applications that are still under investigation, e:g: district heating or cooling systems, hydronic systems in buildings, sewers,irrigation, industrial processes, etc. Our efforts have focused on two main areas: (A) experimental research on momentum and heat transferof turbulent flows of drag-reducing solutions, and (B) implementation of these solutions in hydronic cooling systems in buildings for energyconservation purposes. This paper describes an overview of the typical experimental research that we conduct in our non-Newtonian fluidmechanics, rheology, and heat transfer laboratory at UCSB 2006 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57065310 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
