dot-get_gh: g_h: boundary layer conductance to heat (m / s)

In cdmuir/tealeaves: Solve for Leaf Temperature Using Energy Balance

g_h: boundary layer conductance to heat (m / s)

Description

g_h: boundary layer conductance to heat (m / s)

Usage

.get_gh(T_leaf, surface, pars, unitless)

Arguments

T_leaf	Leaf temperature in Kelvin
surface	Leaf surface (lower or upper)
pars	Concatenated parameters (leaf_par, enviro_par, and constants)
unitless	Logical. Should function use parameters with units? The function is faster when FALSE, but input must be in correct units or else results will be incorrect without any warning.

Details

g_\mathrm{h} = D_\mathrm{h} Nu / d

Symbol	R	Description	Units	Default
d	leafsize	Leaf characteristic dimension in meters	m	0.1
D_\mathrm{h}	D_h	diffusion coefficient for heat in air	m^2 / s	calculated
Nu	Nu	Nusselt number	none	calculated

Value

Value in m/s of class units

Examples

library(tealeaves)

cs <- make_constants()
ep <- make_enviropar()
lp <- make_leafpar()

T_leaf <- set_units(298.15, K)

tealeaves:::.get_gh(T_leaf, "lower", c(cs, ep, lp), FALSE)
