Abstract:
A method is provided for monitoring a flow behavior of mixed components without requiring additional instrumentation or sampling. The method is carried out by determining ratios of the power required to rotate a mixing impeller at different rotational speeds and then comparing the ratios. Characteristics about the mixed components are determined based on differences between the ratios.

Claim (Index 1):
A control system for monitoring a flow behaviour of mixed components, comprising:\n a memory for storing a relationship between a Reynolds number N Re  and a Power number N p  for at least one used mixing system geometry; an input means adapted to receive data regarding at least one of the speed N of the mixing impeller and the power P required to rotate the mixing impeller; a speed control means which is adapted to control the speed of the mixing impeller; a determining means which is adapted to:\n determine a quantity \n P i N i 3 at various speeds N i  of the mixing impeller and compare two subsequently calculated quantities in order to determine whether the difference is within a specified range to determine whether the flow of the components in the mixing vessel is a turbulent flow, wherein N i  is the speed at which the mixing impeller rotates and P i  is the power required to rotate the mixing impeller at the speed N i ;\n determine the density \u03c1 of the mixed components based on at least one speed N i  for which the flow is determined to be turbulent by the following formula: \n \u03c1 = P i N P , constant \ue89e N i 3 \ue89e D 5 wherein \u03c1 is the density, P i  is the power required to turn the mixing impeller at the speed N i , N P,constant  is the Power number for a used mixing system configuration, N i  is the speed at which the mixing impeller rotates and D is the diameter of the mixing impeller; determine the Power number N P,variable  for at least one detected speed N j  at which the flow is determined to be non-turbulent by the following formula: N P , variable = P j \u03c1 \ue89e \ue89e N j 3 \ue89e D 5 wherein P j  is the power required to rotate the mixing impeller at the speed N j , \u03c1 is the density previously determined based on N P,constant , N j  is the speed at which the mixing impeller rotates, and D is the diameter of the mixing impeller; and to determine the dynamic viscosity \u03bc of the mixed components by the following formula: \u03bc = \u03c1 2 \ue89e N j 5 \ue89e D 6 x T \ue89e P j wherein \u03c1 is the calculated density, N j  is the speed at which the mixing impeller rotates, D is the diameter of the mixing impeller, P j  is the power required to rotate the mixing impeller at the speed N j  and x T  corresponds to a specified relationship between the Reynolds number for the used mixing system configuration and the determined Power number N P,variable .
