Recent reviews of the literature on thermoregulation during exercise including the regulation of thermal sweating have been made by many scientists [see (1) for Jessen's review]. Human body temperature is determined by the balance between heat accumulation, whether generated by physical activity (metabolic heat production) or gained from the environment (environmental heat), and heat dissipatio...

Based on the recently introduced fractional Taylor’s formula, a fractional heat conduction constitutive equation is formulated by expanding the single-phase lag model using the fractional Taylor’s formula. Combining with the energy balance equation, the derived fractional heat conduction equation has been shown to be capable of modeling diffusion-to-Thermal wave behavior of heat propagation by ...

Actual evapotranspiration is assessed via surface energy balance at an hourly rate. However, a robust estimation of daily evapotranspiration from hourly values is required. Outcomes of surface energy balance are frequently determined via measures of eddy covariance latent heat flux. Surface energy balance can be applied on images acquired at different times and spatial resolutions. In addition,...

Metabolic heat production (calculated from oxygen consumption), dry heat loss (measured in a calorimeter) and body temperature (measured by telemetry) were recorded simultaneously at 6 min intervals over five consecutive days in rats maintained in constant darkness. Robust circadian rhythmicity (confirmed by chi square periodogram analysis) was observed in all three variables. The rhythm of hea...

The interaction between urban heat islands (UHIs) and heat waves (HWs) is studied using measurements collected at two towers in the Beijing, China, metropolitan area and an analytical model. Measurements show that 1) the positive interaction betweenUHIs andHWs not only exists at the surface but also persists to higher levels (up to ;70m) and 2) the urban wind speed is enhanced by HWs during day...

Adequate heat balance is critical to human performance in the heat. If heat balance cannot be maintained, the core temperature increases and body water dehydration leads to exhaustion and limit the performance. Clothing heat transfer properties, thermal insulation and water vapour resistance, modify heat exchange and may indirectly affect performance. Work in protective clothing quickly becomes...

In this paper, Adomian decomposition sumudu transform method is introduced and used to solve the temperature distribution in a solid and porous fin with the temperature dependent internal heat generation for a fractional order energy balance equation. In this study, we assume heat generation as a variable of fin temperature for solid and porous fin and the heat transfer through porous media is ...

A number of fixed grid finite element methods were tested on problems involving heat conduction with phase change. Only methods that can deal with arbitrary enthalpytemperature relationships were considered. Comparisons were made of temperature gradient vs enthalpy gradients formulations, lumped vs distributed capacitance, timeaverage vs space-average apparent heat capacity, iterative vs non-it...
