Single grain kernel model results

This data is from a model developed, which predicts the mass and heat transfer in a grain kernel. The model is based on the work of Fortes et.al. (1981), where four different drying conditions are tested and validated with experimental data. The data given is the moisture content and temperature in a grain kernel being dried under the four different conditions. The initial conditions, properties and geometry are as presented in Fortes et.al. (1981). M. FORTES; M. R. Okos; J. and R.

Thermal and Ventilation Performance Assessment in Traditional Islamic Hospitals Based on Computational Fluid Dynamics Simulation, Case Study: Bimaristan Al-Qaimari - Damascus

This Study aims to examine natural ventilation efficiency and thermal performance in traditional Islamic hospitals. It assesses the effect of various design variables on indoor ventilation, thermal efficiency in patients’ wards in traditional Islamic hospitals taking into consideration seasonal weather conditions (summer-winter), and to which extent these buildings adapts climate change passively. Investigative analysis associated with evaluative approach was drawn to study ambient air behavior in courtyard space and larger urban context, and its influence on indoor ventilation and thermal efficiency in patients’ wards. This will clarify how air moves passively using architectural elements (vaults, courts, openings, water elements) using CFD software to conduct graphical and numerical simulations and to correlate related variables with airflow behavior. These findings will be evaluated according to ventilation standards. Bimaristan Al-Qaimari was chosen as a typical sample of traditional Islamic hospitals. CFD model was built and CFD snapshots were taken in reference to Energy+ thermal analysis on specific times to represent typical summer day and typical winter day. The data was categorized according to seasons (summer-winter), architectural elements used in hospital and ventilation efficiency using CFD to assess ventilation efficiency in these spaces. This study is looking forward to determine the design parameters’ effects of traditional Bimaristans on ventilation and thermal efficiency to make better environment for patients’ health by learning from past lessons in traditional Islamic architecture

Natural ventilation feasibility in typical patients wards in a Belgian hospital during summer

Natural ventilation is an interesting topic of research. It could contribute in supplying adequate airflow rates, achieving thermal comfort in patients’ wards in hospitals and reduce energy consumption. Although, it’s still challenging due to the high fluctuations in ambient airflow and changeable weather conditions which should be studied carefully to be able to achieve stable and comfortable thermal conditions in patients’ wards. This study investigates the feasibility of integrating natural ventilation with existing HVAC system, when it’s possible to have natural ventilation as an efficient alternative and to which extent could we use natural ventilation in summer. This will be explored using Ecotect weather tool thermal simulation model and computational fluid dynamics using DesignBuilder. Picardy Wallonia Medical Center was chosen as a case study since it was precisely designed to benefit from natural ventilation and all windows in patients’ wards could be opened to benefit from ambient air. Moreover, it contains two typical prototypes of patients’ wards: single-bed ward which presents the present orientation in patient ward design, and a creative multiple-bed prototype which was designed to achieve better functional design solutions and more comfortable thermal conditions. The expected results of metrological analysis will evaluate ambient weather suitability for natural ventilation and how some uncomfortable conditions could be solved using passive techniques. Based on metrological analysis single patient ward will be subjected to CFD simulation to investigate their actual ventilation performance when windows are open when natural ventilation is a potential. This study will be useful for designers and HVAC engineers to give them a perspective regarding natural ventilation as a potential in ward design. Also it will be useful for standards organizations to have a deeper look regarding natural ventilation margins in patients’ wards in hospitals
