1. The reduction of turbulent drag of fluids flowing through conduits such as pipelines, channels, troughs and streams, or of drag on an object which is moving relative to a fluid, which comprises adding to said fluid a mixture of soluble polymeric substances and of suspended fibers. 2. Process fluids, consisting of the above-mentioned mixtures of dissolved polymers and suspended fibers, which exhibit decreased pressure losses under conditions of turbulent flow as compared to the carrier liquid but which exhibit heat or mass transfer rates which are of the same magnitude as those of the unmodified carrier liquid. That is, process fluids for which the heat transfer rate per unit of pumping power required is greater than that exhibited by the carrier fluid.
A process for reducing the turbulent drag of a fluid in a conduit or around a submerged object which comprises adding to the fluid a soluble polymer and a dispersable non-soluble fibrous substance having an aspect ratio of at least 100.
A process, having as either its primary or important secondary purpose, the transfer of heat and/or mass from a process fluid stream in which a dissolved polymer and a dispersed non-soluble fibrous substance having an aspect ratio of at least 100 are added to the process fluid for the purpose of reducing the turbulent pressure drop required to pump the fluid stream.
