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 Cp, b, 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.
