摘要
Abstract
Pasty propellant simulacrum pipe flow experiment shows that wall slip has great effect on the flow diagram. By fitting a number of flow test diagram, wail slip correction factor was obtained. Hence comes flow increment of wall slip and generalized Reynolds number which including effect of wall slip. Results show that flow parameters of pasty propellant simulacrum after correction are consistent with the rotary rheometer test data. It is helpful to prove the reliability of the correction method used. Meanwhile , having the generalized Reynolds number with wall slip effect for Reynolds number without the effect, the calculation of pressure drop along pasty propellant delivery pipeline could be in unified form.关键词
