Using a miniature sloped greenhouse and model plants, temperature profile measurements and flow pattern observations within the house were performed. Flow pattern was observed using ammonium chloride aerosol as a tracer, which was inserted from windows on the side cover film of the house. Heat and momentum transfers in the sloped greenhouse with plants were formulated applying the simplest turbulent model, 0-equation model. According to the model's numerical solutions, the calculated results of the temperature profile agreed well with the experimental results, both qualitatively and quantitatively. The calculated results of air velocity in the house were in the same order as the experimental results. However, two coefficients relating to the flow resistance of the air within the plant layer, the specific air permeability and the dispersion coefficient, must have been calculated using the trial and error technique, out of necessity. It is advisable and necessary to consider precise estimation methods for these coefficients, and to make clear the validity for applying this model to a practical scale sloped greenhouse with plants.
