Greenhouse Climate: uses and methods
Observe the relationship between ventilation intensity and temperature distribution under restricted geometry.
Applicable scope and calculation boundary
A two-dimensional steady-state convection-diffusion thermal model driven by a fixed fan jet parameter field; 3D is a transverse uniform extrusion display. Without solving Navier–Stokes, engineering CFD predictions cannot be made.
model and reference method
u·∇T=κ∇²T+S; first-order windward convection, central diffusion, sparse linear solution.
