In order to identify friction-reducing additives that have a reasonable lifetime at DHC temperatures, screening and degradation tests of two high-molecular-weight linear-polymer additives and three fibers have been performed. An important discovery in this study is that with flow shear similar to that encountered in practical DHC pipe flow Separan is highly effective and have a reasonable lifetime at DC temperatures. Also, synthetic fiber is a promising additive capable of reducing frictional pressure drop at district heating and cooling temperatures. Testing in a large scale DHC system simulator will be conducted to study the effect of high flow shear in a centrifugal pump on the degradation of promising additives. 8 refs., 8 figs.
