ThermalMedium

Package: kwave.toolbox Superclasses: kwave.toolbox.GridInput

Class used to define the thermal medium properties for a simulation.

Syntax

kgrid = Grid([128, 128], 1e-3);
medium = ThermalMedium(kgrid);
medium.density = rand(medium.gridSize);

Description

This class is used to define the thermal medium properties. The constructor takes an object of the kwave.toolbox.Grid class which defines the grid size. All medium properties can be scalar or have the same size as the grid. The density, specificHeat, and thermalConductivity must be defined.

Examples

Define the grid and medium objects, and assign the thermal properties.

  kgrid = kwave.toolbox.Grid([128, 128], 1e-3);
  medium = kwave.toolbox.ThermalMedium(kgrid);
  medium.density = rand(medium.gridSize);
  medium.specificHeat = rand(medium.gridSize);
  medium.thermalConductivity = rand(medium.gridSize);

Properties

• density - (numeric) Mass density [kg/m^2].
• diffusionReference - (numeric) Reference diffusion coefficient used in the k-space correction term [m^2/s]. Automatically defined in ThermalSolver if not defined by the user.
• specificHeat - (numeric) Specific heat capacity at constant pressure [J/kg/K].
• thermalConductivity - (numeric) Thermal conductivity [W/m/K].
