“…For this reason no parametric study relative to Q met and w was presented. Numerical observation confirms the works of [13], [14], [15] which suggest that the effects of the perfusion rate are significant in the case of long life thermal exposures and of low intensity or in the case of microwave exposure [16].…”

Abstract.One of the long-term objectives of this study is to be able to act quickly on body burns, to avoid propagating lesions due to heat diffusion. An experimental and numerical study is presented to better understand the thermomechanical behavior of the skin and its direct environment when exposed to strong thermal variations. The experimental step, suggested in this article, consists in placing a cooled cylindrical steel bar on the skin of a human forearm and measuring the temperature change using an infra-red camera. Blood circulation in the veins was seen to clearly influence of the heat diffusion. These experimental measurements provide a numerical model of the skin and its direct vicinity. This two-dimensional multi-layer model uses the Pennes equation to model biological tissue and the equation of heat in a fluid, to model blood. The properties of materials from the literature are validated by experimentation. The numerical model is able to simulate the experimental observations, but also to estimate blood speed in the veins.

“…The analytical results for a low continuous heat flux describe that when the blood perfusion rate increases, the increasing rate of temperature in the skin decreases. Ozen et al [8] studied thermal wave model of bio-heat transfer. As a model, skin stratified as three layers with various thermal physical properties were simulated, and thermal wave model of bio-heat transfer equations were solved by using finite difference method.…”

In this paper, the temperature distribution in a finite biological tissue in presence of metabolic and external heat source when the surface subjected to different type of boundary conditions is studied. Classical Fourier, single-phase-lag (SPL) and dual-phase-lag (DPL) models were developed for bio-heat transfer in biological tissues. The analytical solution obtained for all the three models using Laplace transform technique and results are compared. The effect of the variability of different parameters such as relaxation time, metabolic heat source, spatial heat source, different type boundary conditions on temperature distribution in different type of the tissues like muscle, tumor, fat, dermis and subcutaneous based on three models are analyzed and discussed in detail. The result obtained in three models is compared with experimental observation of Stolwijk and Hardy (Pflug Arch 291:129-162, 1966). It has been observe that the DPL bio-heat transfer model provides better result in comparison of other two models. The value of metabolic and spatial heat source in boundary condition of first, second and third kind for different type of thermal therapies are evaluated.

“…When the rate of energy absorption is high it produces heating effects in the living tissues (Ozen et al, 2009). The biological effects of radiofrequency energy depend on the rate at which power is absorbed (Osepchuk and Petersen, 2003).…”

Abstract:The mathematical calculation of change in temperature of skin, blood, muscle and bone tissues of human being working at the frequency of 800, 900, 1800 and 2450 MHz is done in this manuscript. The power of the antenna of mobile phone is of 2 W. The calculation is made at the various depths, by taking the different distances of human body from the mobile phone. The depth of penetration is ranging from 0.1 to 0.5 mm inside the body tissues. The thermoregulation system of the body can maintain the body temperature but at some extent. Variation of change in temperature due to the exposure of 15, 30, 45 and 60 min in selected tissues is also analysed.
