Bioheat
This feature provides the source terms that represent blood perfusion and metabolism to model heat transfer in biological tissue using the bioheat equation:
Bioheat
Enter values or expressions for these properties and source terms:
Arterial blood temperature Tb, which is the temperature at which blood leaves the arterial blood veins and enters the capillaries. T is the temperature in the tissue, which is the dependent variable that is solved for and not a material property.
Specific heat, blood Cpb, which describes the amount of heat energy required to produce a unit temperature change in a unit mass of blood.
Blood perfusion rate ωb (SI unit: 1/s, which in this case means (m3/s)/m3), describes the volume of blood per second that flows through a unit volume of tissue.
Density, blood ρb, which is the mass per volume of blood.
Metabolic heat source Qmet, which describes heat generation from metabolism. Enter this quantity as the unit power per unit volume.
