“…They identified that each turbulence models have their advantages and limitations under different situations, and that no universal turbulence model exist for indoor airflow simulations. Tanasic et al [20] investigated the airflow in a mechanically ventilated large industrial hall, including buoyancy, using the standard k-ε model for turbulence. They concluded that the model did not provide adequate quantitative results as the simulation values differed significantly from the measured values.…”

“…This result indicates a good agreement between simulation modelling and field measurements, which stated the deviation (%) for air velocity is less than 20%. Similarly, previous studies revealed that air velocity's deviation (%) less than 20% is accepted for CFD validation with field measurement [40,48,49]. The air velocity (m/s) at P4 is lower than P3 at 0 • wind angle compare to the one at 45 • wind angle.…”

Abstract:Enhancing natural ventilation performance in multi-storey housing is very important for the living environment in terms of health and thermal comfort purposes. One of the most important design strategies to enhance natural ventilation in multi-storey housing is through the provision of voids. A void is a passive architectural feature, which is located in the middle of deep plan buildings. It is very crucial to consider the configurations of voids in the buildings for enhancing natural ventilation, especially for multi-storey housing. In this study, Malaysian Medium Cost Multi-Storey Housing (MMCMSH), which is an example of multi-storey housing located in a suburban area, has been selected in this study. This study aims to investigate the potential of void for enhancing natural ventilation performance in multi-storey housing by the comparison of two different void configurations. Field measurement of MMCMSH has been conducted to validate Computational Fluid Dynamic (CFD) model and Atmospheric Boundary Layer (ABL) is an important parameter for setting up the CFD Model's domain. Ventilation rate (Q), which is necessary for comfort and health reasons, is an important parameter for the comparison of the different void configurations. This study revealed that the provision of void can enhance natural ventilation performance in multi-storey housing with an increase in the value of Q, from 3.44% to 40.07%, by enlarging the void's width by 50% compared to the existing void.

Abstract:The drying process of paper has many production parameters that can influence both the energy consumed and the characteristics of paper produced. It was found that most of the previous studies conducted on this process assume that the conditions of the facilities are always appropriate. The control of the variables associated with air circulating inside the drying hood is essential to obtain a paper with adequate quality and obtain low ratios of energy consumption and CO 2 emissions. This article proposes a new indirect method based on the study of the enthalpy of the airflows inside the production hall and thermographic images that helps to analyze the maintenance state of the enclosure hood drying section in a general process, whereby it can also estimate the emissions and energy losses. The combined use of sensors and equipment has helped to identify energy losses and potential savings in CO 2 emissions. The developed method is applied to a paper manufacturing plant that has ratios of energy consumption and CO 2 emissions very close to the product benchmark set by the European Authorities. The study corroborates that it can be identified as a significant energy loss in paper making drying process. Analyzing facilities that are in apparently good maintenance conditions, leaks are evident. These energy losses are very significant compared with the theoretical energy consumption, and it can affect the paper moisture profile.
