  • Does polyacrylamide drag reducing agent affect friction factor and heat transfer coefficient?
  • The effect of polyacrylamide drag reducing agent on friction factor and heat transfer coefficient in laminar, transition and turbulent flow regimes in circular pipes with different diameters. Int.
  • What is drag reduction in drilling fluid system?
  • DRAs (friction reducers) are one of the essential components of the drilling fluid system. The drag reduction induced by DRA makes it possible to inject the drilling fluid at the high injection rate required for efficient hole cleaning with limited pump capacity. It also helps in maintaining the pumping equipment and flowlines associated with it.
  • What is a drag reducing agent?
  • Drag reduction is required to increase the flow capacity and pumping rate, and drag-reducing agents (DRAs) are usually added to the fluids to reduce the drag. DRAs are defined as additives that are added to the fluids to reduce the drag on the pipe wall.
