Qconvection: Organismal Convection

In TrenchR: Tools for Microclimate and Biophysical Ecology

Organismal Convection

Description

The function calculates convection from an organism to its environment as in \insertCiteMitchell1976;textualTrenchR. It includes an enhancement factor associated with outdoor environments.

Usage

Qconvection(T_a, T_b, A, proportion, H_L = 10.45, ef = 1.23)

Arguments

T_a	numeric air temperature (K).
T_b	numeric initial body temperature (K).
A	numeric surface area (m2).
proportion	numeric proportion of surface area exposed to air.
H_L	numeric convective heat transfer coefficient (W K-1 m-2).
ef	numeric is the enhancement factor, used to adjust H to field conditions. Approximated as mean value of 1.23 by default, but see \insertCiteMitchell1976;textualTrenchR for further information.

Value

numeric convection (W).
