Abstract:

Finite element method with Crank-Nicolson technique is employed to investigate one dimensional temperature distribution in human skin and subcutaneous tissue (SST) exposed to cold environmental temperature and wind flow. The wind speed is considered in the range from the start of forced convection ( 0.2 m/s) and up to 5 m/s. The important parameters like blood mass flow rate, metabolic heat generation rate and thermal conductivity are taken distinct in the layers of SST. The values of these parameters are considered as position dependent in the layers. The loss of heat from the body is considered due to convection, radiation, and insensible perspiration.
