摘要

温室农业超越了传统农业的限制，通过可控的环境显著提高了农业生产的效率和可持续性。针对温室小气候控制中热动力平衡的难题，提出了一种将能量方程与可实现的k-epsilon湍流模型相结合的多物理场耦合模型，用于模拟玻璃温室内温度和风速的分布。本文主要研究了多孔介质、太阳辐射和送风射流风速对温室小气候系统温度和风速分布的影响。在数值模拟中，给出并详细讨论了不同配置下温室温度场和风速场的分布。数值模拟结果表明，多孔介质在温室内具有调节温度和稳定风速的重要作用。此外，引入植物生长适宜度作为数值评价指标，对小气候调控系统进行定量评价。本文可以为玻璃温室的部署提供有价值的帮助，为温室栽培行业提供有价值的见解。

A numerical simulation of microclimate regulation using multi-physics fields coupling model

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.
