CIMP Software Status: TM-5

TM-5-A (6/86)

simplex program for fitting viscosity data with 4-constant (n, tau*, B, Tb) model

5-A-P (6/86)

software used to plot data and resulting fit from 5-A

5-B (6/86)

fits capillary-rheometer viscosity data with due regard for viscous heating and pressure dependence by combining simplex method with finite-difference simulation of steady non-isothermal flow in tube; generates values for either 5-constant (n, tau*, B, Tb, beta) or 7-constant (n, tau*, D1, D2, D3, A1, A2 or à 2) models ...superseded by 5-D

5-B-P (6/86)

software used to plot data and resulting fit from 5-B

5-C (6/86)

same as 5-B but neglects viscous heating & assumes power-law fluid (but with pressure dependence) such that finite-difference simulation of 5-B gets replaced by closed-form result

5-C-P (6/86)

software used to plot data and resulting fit from 5-C

5-D (6/89)

program PLEX3EM2 which is an extension of 5-B to include juncture losses via (delta)Pe = C1*(tau-w0)^C2 where (tau-w0) denotes wall shear stress at capillary entrance; accordingly, program performs Bagley and Weissenberg-Rabinowitsch corrections with due regard to pressure dependence and viscous heating (note: unlike 5-B, this up-graded version does not handle the double-piston pressurized capillary rheometer of Westover); superseded by PLEX3EM7

5-D-P (6/89)

software used to plot data and resulting fit from 5-D in terms of (delta)P versus gamma for fixed inlet temperature and die (i.e. each curve corresponds to fixed To, L/D and D); superseded by PLX3E7-P
