Transient And Steady State

The shock effect has been analyzed when the human body touches different types of vehicles in power frequency electric field. It solved the problem of influence of induced voltage generated by high voltage AC Power Lines on human Body. The induced voltage value of the human body and three different types of vehicles has been calculated by the soft of ANSYS in this paper. The results indicate that the human body will be shocked by two processes of transient and steady state. The influence of shock effect of transient and steady state on human body has been selectively analyzed when the human body touches vehicles. The proposed models and algorithm has the advantages of simple calculation procedure, small calculation burden and convenient to engineering application. It can be applied to the shock effect when the human body touches metal objects with different potential in power frequency electric field. It is worth being populated.

Based on the basic theory of electromagnetic field, the Electric Field Distortion (EFD) in power frequency electric field caused by induced current of human body has been analyzed. The enhancement factor of the electric field distortion is introduced to reduce the influences caused by human body in the measurement of high voltage electric fields. The Ansoft Maxwell is used to simulate and calculate the electric field distribution under the influence of the human body to have the value of enhancement factor. In addition, the enhancement factor has been corrected by experiment with the electromagnetic field analyzer EFA300. With the enhancement factor introduced in this paper, the measurement error can be reduced.

The composition of fluid distribution in human body is consisting of various intra-cellular and extra-cellular fluids. Dehydration and other changes in the system may lead to various disorders and diseases in the normal functioning. It is therefore imperative to study the fluid distribution and its balance in the human body systems. In this study, we estimate the pattern of fluid in human dermal regions with heterogeneous metabolic fluid generation. The model is based on radial diffusion equation with appropriate boundary and interface conditions. The variational finite element method has been used to solve the model. The results of fluid concentrations at the dermal and subdermal regions were calculated and interpreted graphically at various levels of humidities and perspirations.
