Abstract
Greenhouse agriculture transcends the constraints of traditional farming, significantly enhancing the efficiency and sustainability of agricultural production through a controlled environment. Aiming at the challenges of thermal dynamic balance in microclimate control within greenhouses, a multi-physics field coupling model is presented for modeling the distribution of temperature and wind speed inside a glass greenhouse, in which the energy equation is integrated with the realizable k-epsilon turbulence model. This article is focused mainly on the influence of porous media, solar radiation, and wind speed of air supply jets on the distribution of temperature and wind speed in greenhouse microclimate systems. In numerical simulations, the distribution of greenhouse temperature and wind speed fields under different configurations is presented and discussed in detail. Numerical simulations indicate that porous media plays an important role in regulating temperature and stabilizing wind speed in greenhouses. In addition, a plant growth suitability rate as a numerical evaluation index is introduced to quantitatively assess the microclimate regulation system. This article can provide valuable assistance for deploying glass greenhouse, offering valuable insights for the greenhouse cultivation sector.
期刊介绍:
International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
