Greenhouse Natural Ventilation Models: How Do We Develop with Chinese Greenhouses?

open access: yesAgronomy, 2022
Greenhouse technology has advanced over the past few decades in terms of environmental control (e.g., indoor temperature, relative humidity, and CO2 concentration). Ventilation is an effective way to adjust the indoor climate.

Buoyancy driven rotating boundary currents [PDF]

open access: yes, 1997
The structure of boundary currents formed from intermediately dense water introduced into a rotating, stably stratified, two-layer environment is investigated in a series of laboratory experiments, performed for Froude numbers ranging from 0.01 to 1. The

Exergo-Economic Evaluation of the Cost for Solar Thermal Depuration of Water

open access: yesEnergies, 2017
A detailed assessment of the cumulative cost of clean water production by a natural circulation solar thermal system is presented. The system is designed and sized for sufficient residence time for pasteurisation, in a buoyancy-driven self-compensating ...
