Description

The Liquid Properties Sensor (IL) block represents an ideal sensor that lets you measure the mixture density, bulk modulus, fraction of entrained air, dynamic viscosity, and kinematic viscosity in an isothermal liquid network. There is no mass flow through the sensor.

The block measures these properties at the node connected to port A.

Ports

Output

ρ — Density measurement, kg/m^3

physical signal

Physical signal output port that measures the density of isothermal liquid mixture.

Dependencies

To enable this port, select the Density check box.

β — Isothermal bulk modulus measurement, Pa

physical signal

Physical signal output port that measures the bulk modulus of isothermal liquid mixture.

Dependencies

To enable this port, select the Isothermal bulk modulus check box.

θ — Fraction of entrained air measurement, unitless

physical signal

Physical signal output port that measures the fraction of entrained (undissolved) air, (entrained air)/(entrained air + dissolved air). Value of 1 means no air is dissolved. Value of 0 means all air is dissolved.

Dependencies

To enable this port, select the Fraction of air that is entrained check box.

μ — Dynamic viscosity measurement, Pa*s

physical signal

Physical signal output port that measures the dynamic viscosity of isothermal liquid mixture.

Dependencies

To enable this port, select the Dynamic viscosity check box.

ν — Kinematic viscosity measurement, m^2/s

physical signal

Physical signal output port that measures the kinematic viscosity of isothermal liquid mixture.

Dependencies

To enable this port, select the Kinematic viscosity check box.

Conserving

A — Sensor inlet

isothermal liquid

Isothermal liquid conserving port. Connect this port to the node in the isothermal liquid network where you want to measure the liquid properties. All measurements are taken with respect to absolute zero.
