The paper begins with a brief review of earlier work. The 1990s saw limited extensions to the
theory, computer modelling and practices relating to light transmission, apart from an …

The use of screens to reduce insect entry into greenhouses has become a common practice
in many countries. The screens act as a mechanical barrier that prevents migratory insects …

If growers want to produce a healthy crop, with good quality and high yield, they have to
provide appropriate climatic conditions for crop production inside the greenhouse. Night …

An analysis of the ventilation process in a tunnel greenhouse equipped with an insect-proof
screen in the side openings was performed with the use of a commercial computational fluid …

Experiments and analyses were conducted to examine the airflow characteristics of some
currently employed greenhouse screens and the ability to predict airflow through them. Nine …

The wind coefficient of an Almería-type greenhouse has been calculated from direct
estimation of airflow at the openings by means of three-dimensional sonic anemometry …

The object of this work was to determine and model the air exchange rate of greenhouses
with insect-proof screens over the vents. Experimental tests were conducted on multi-span …

Measurements of the discharge coefficients of ventilation openings with aspect ratios
between 1 and 36, and with and without flaps attached by a hinge along one side, were …

Experimental data from a wind tunnel, was used to compare three available methods to
predict the pressure drop through screens. Advantages and drawbacks of each method are …

A field experiment was carried out to study the microclimate and air exchange rate of an
insect-exclusion fine-mesh 60m by 110m by 3· 2m commercial screenhouse for pepper …
