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 climate. Natural ventilation gained significant research attention recently because its low energy requirement. To evaluate effectiveness, rate often used. This review summarizes published p...

A precise wind power prediction is important for the integration of wind energy into the power grid. Besides numerical weather models for short-term predictions, there is a trend towards the development of statistical data-driven models that can outperform the classical forecast models [1]. In this paper, we improve a statistical prediction model proposed by Kramer and Gieseke [5], by employing...

UCHIYAMA, Y., 2007. Hydrodynamics and associated morphological variations on an estuarine intertidal sand flat. Journal of Coastal Research, 23(4), 1015–1027. West Palm Beach (Florida), ISSN 0749-0208. Hydrodynamics, sediment suspension, and morphological response on an estuarine intertidal sand flat in Tokyo Bay, Japan, are examined through a field experiment performed for 16 days in winter 20...

The neutrino driven wind during a core collapse supernova is an attractive site for r-process nucleosynthesis. The electron fraction Ye in the wind depends on observable neutrino energies and luminosities. The mean antineutrino energy is limited by supernova SN1987A data while lepton number conservation constrains the ratio of antineutrino to neutrino luminosities. If Ye, in the wind, is to be ...

Abstract Computational fluid dynamics analysis of a building plan has been investigated with predominant wind velocity for different directions. The flow properties’ variation in the computational domain modeled by solving Reynolds-Averaged Navier–Stokes (RANS) equations finite volume second-order discretization scheme. turbulence airflow distribution and around Shear Stress Transport (SST) k–ω...

Despite the similar performance of Bazaar1 in different cities of Iran, there are some the skeletal differences between markets in different climates. The Bazaar roof protects customers against natural events in any climate. The ceiling height and the sitting down of the Bazaar`s floor are determined based on the need for air circulation and movement in various climates. Hence, combination of a...

Mechanical Heating Ventilation and Air-Conditioning (HVAC) systems account for 60% of the total energy consumption of buildings. As a sector, buildings contributes about 40% of the total global energy demand. By using passive technology coupled with natural ventilation from wind towers, significant amounts of energy can be saved, reducing the emissions of greenhouse gases. In this study, the de...

The ventilation index serves as a theoretically based metric to assess possible changes in the statistics of tropical cyclones to combined changes in vertical wind shear, midlevel entropy deficit, and potential intensity in climate models. Model output from eight Coupled Model Intercomparison Project 5 models is used to calculate the ventilation index. The ventilation index and its relationship...
