What Is Pennes Equation?
The Pennes equation is named after bioengineering scientist Carl Gunnar Pennes. It is a mathematical formulation that describes the transport of heat in biological tissues due to blood perfusion. It is commonly used in medical applications to understand the transfer of heat in tissues during hyperthermic treatments for cancer, thermotherapy, and other thermal treatments. The equation describes how blood flow affects the temperature in biological tissues and considers physiological parameters such as blood flow rate, thermal conductivity, specific heat capacity, and metabolic heat generation.
