An Unsteady Mathematical Model of Human Dermal Region Due to Temperature Distribution of Artirel Blood Flow in Cold Atmosphere

Yogesh Shukla, Sonia Shivhare

Abstract: This paper deals with the change in ambient temperature which can adversely disturb the thermostat in human body. Acute thermal disorders above and below the normal range of body temperature are termed as hyperthermia and hypothermia thermo-regulation in human dermal region. A one dimensional temperature distribution model in human dermal region involving bio-heat equation has been solved using finite element method the natural three layers of dermal part epidermis; dermis; and subcutaneous tissues are considered for the study. The important parameters like blood mass flow rate; metabolic heat generation rate and thermal conductivity are taken in each layer. The loss of heat from the skin surface to the environment is taken due to convection; radiation; and insensible perspiration.
