Lecture 10. Surface Energy Balance (Garratt 5.15.2)
2016427 The last example is a Douglas fir forest (Fig. 10.4). Here latent and sensible heat fluxes are comparable during the day. The storage and ground heat flux are lumped in the curves, but for deep forest, the storage term dominates. At night, release of heat from the tree canopy and condensation (dew) balance radiative energy loss.

CHAPTER 2 Steam Generators
2017322 maximum heat flux, qmax, i.e., point E in Figure 2.3, is also useful as this represents an upper limit in the nucleate boiling heat transfer. The following formula, from Roshenow and Griffith, gives the value of qmax in SI units, i.e., W/m2 [3]. Once the critical heat flux data is determined it is compared with the required heat flux data.
