Took a typical soil-walled passive greenhouse located in Jinan, Shandong, China as an example, an unsteady tri-dimensional numerical simulation was applied to solve the temperature and humidity profiles under natural ventilation conditions inside the greenhouse, based on the CFD program.
The simulation results agree well with test values about the temperature and humidity inside the greenhouse with fitting degree of 99.8% and 99.7%, respectively.
With the development of computer technology, computational fluid dynamics (CFD) software becomes a powerful tool to study the spatial distribution of thermal and moisture environment in greenhouse.
The simulation results and the experimental data of greenhouse operating parameters which include the indoor air temperatures as well as the RH are compared for validation, as shown in Figures 1 and 2.

Temperature Analysis in Durability Test of the Viscous Damper Wang weining 1, a, Yan Weiming 1,b , Chen Yanjiang 1,c 1 School of Architecture and Civil Engineering, Beijing University of Technology, 100124, Beijing, China awangvn@hotmail.com, byanwm@bjut.edu.cn, acyjrlx@sina.com Keywords: Viscous Damper; Oil film; CFD Thermal; Temperature; Abstract.
In order to avoid the overheating generated by long working hours, which resulting in a viscous liquid water evaporation and leading to a abrupt increase in internal pressure inside the cylinder, the CFD software Fluent was used to simulate the durability test process of the oil film, where the heat was easy to generate and suggestion for improving the viscous damper was proposed.
Numerical Simulation Analyses As above mentioned, heat generated in cylinder and consumed mainly through viscous dissipation and internal friction.
On the basis of above analysis, CFD software Fluent was used to simulate the heat generation process and location in damper and determinate the key factors leading to elevation of the cylinder temperature.
Fig.3 Location Diagram of the Simulations In modeling, considering that the working velocity in the durability test should not be over 1m/s, and taking into account of width of the orifice and the viscosity of the fluid, the Reynolds number should be <2000[5], therefore Laminar flow model was adopted.
