We present a method that can be used to optimize CFD analyses of ventilation performance in buildings; the method was successfully applied in other disciplines. In the method, three statistical methods are used - the Taguchi method, ANOVA, and Grey Relational Analysis (GRA) to achieve optimization. We then model the risk of draft and the mean age o...

COVID-19 hastalığı SARS-CoV-2 virüsünün neden olduğu bulaşıcı bir hastalıktır. Küresel ölçekte vakaların artması ile 11 Mart 2020'de Dünya Sağlık Örgütü tarafından küresel salgın ilan edildi. Nefes alıp verme, konuşma, öksürme, hapşırma veya şarkı söyleme gibi solunum aktiviteleri yoluyla yayılan enfekte damlacık dağılımı sebebiyle kapalı ortamlard...
Article
In optimizing thermodynamic cycles, selecting the objective function is crucial, and including advanced methods in addition to classical approaches can provide significant advantages to the optimization process. In this study, the condenser temperature, evaporator temperature, and turbine inlet pressure are considered as variables to be optimized i...
Article
This study analyzed the effect of the refrigerant selection, condenser, and evaporator temperature on thermal efficiency, net-work output, second law efficiency, and exergy destruction values obtained with an advanced approach to exergy analysis. The thermal source was considered a low-temperature geothermal resource at 90℃. R11, R123, and R245ca w...
Article
This study investigated the Stirling cycle's thermodynamic parameters using the Taguchi and Taguchi-based grey relational analysis methods. The Taguchi analysis identified the most crucial parameters for each objective (net work output, thermal efficiency, second law efficiency, charge pressure, irreversibility, entropy production), quantifying the...

The novel coronavirus (SARS-CoV-2) outbreak has spread worldwide, and the World Health Organization (WHO) declared a global pandemic in March 2020. The transmission mechanism of SARS-CoV-2 in indoor environments has begun to be investigated in all aspects. In this regard, many numerical studies on social distancing and the protection of surgical ma...
Article
This study aimed to investigate the multi-objective optimization of a Stirling cycle with a mathematical model that takes into account the dead volumes, effects of regenerative losses, and internal irreversibilities on the thermodynamic performance of the cycle. The optimization was carried out using the Artificial Bee Colony algorithm, which is a...

The coronavirus pandemic has caused many deaths and affected societies with social and economic problems as a consequence of its effects. Many different measures were taken to stop or reduce the spread of the virus, like wearing a face mask and reorganizing school activities, transportation, and meetings. As an alternative to these measures, ventil...
Article
Ensuring the thermal satisfaction of people with their environment increases both the quality of life and productivity. In addition, providing the thermal conditions is important to keep energy consumption at an optimum level. Skin temperature is one of the most appropriate parameters to understand the thermal relationship of the human body with th...

In this study, the effect of coating thickness and thermal property on the temperature distribution of an internal combustion diesel piston was investigated numerically. A piston was modeled in three-dimensional, and then a gird independency test was performed. The optimum element number was selected without losing computational accuracy. The thick...
Article
Full-text available
There is no study that investigates triangular guide protrusions including their systematical geometrical changes together with the effects of channel height in the open literature in the context of the authors’ knowledge. Moreover, the number of laminar studies is less than turbulent studies, whereas low velocity or natural convection cases are st...
Article
The coronavirus pandemic has spread all over the world and has greatly affected societies. During the pandemic, closed environments have become a major risk factor. As a result of many studies, it is understood that the small indoor space and insufficient ventilation create a favorable environment for the spread of the virus. In this study, the dis...

Air conditioning systems use about 40% of global energy. These systems are widely used in office rooms and it is known that their performance directly affects the productivity of employees. In this study, air distribution, indoor air quality based on carbon dioxide and thermal comfort are investigated numerically by using a breathing thermal manneq...
Conference Paper
In this study, thermal comfort by means of percent dissatisfaction (PD) in an office room is predicted by computing airflow and temperature fields in an office room with a table and a sitting person. The office room is ventilated with a wall type air conditioning unit for winter condition and the flow is considered to be turbulent, steady, incompre...
