Assessment of Fouling in Plate Heat Exchangers with Machine Learning Algorithms

Ceren VATANSEVER

Fouling is the accumulation of undesired particles on heat transfer surfaces which affects the heat transfer performance of a heat exchanger negatively. The accumulation of these particles prevents heat from being transformed through the heat exchangers by generating a fouling layer-like insulation. The main aim of the thesis is to investigate the machine learning algorithms to classify and predict the fouling status of PHE used in combi-boilers, to generate the background of the predictive maintenance, besides investigating the fouling effect on PHEs in terms of heat transfer and energy consu ...Daha fazlası

Performance Study of Darrieus Turbine Using Numerical Simulation

Abdelrahman ABUALEENEIN

In this study, CFD abilities to handle Darrieus turbine simulation were assessed and validated in light of related experimental and numerical studies. Simulation methodology is based on two-dimensional modeling of a double NACA 0018 bladed, straight blade Darrieus turbine. Modeling approach, meshing procedure, and solution parameters are mentioned and discussed in details. ANSYS fluent 18.2 is used to carry out all simulations. Experimental test’s data from literature [11] are implemented in context of results verification, also, Courant number and y plus analyses were provided. Due to the sim ...Daha fazlası

Geometrical Optimization of Dimpled Double-Pipe Heat Exchangers for Nanofluid-based Natural Circulation Loops Operating at Lower Temperatures

Nur Çobanoğlu

Excessive use of global energy sources causes negative environmental impacts and a reduction in the available energy resources. Therefore, energy efficiency is the main scope of engineering studies. Since household refrigeration accounts for a large portion of the energy consumption rate in buildings, several innovative techniques have been developed to improve the energy efficiency of vapor compression refrigeration systems. Suction line heat exchangers are considered one of these techniques and they are used to avoid the presence of liquid at the compressor and to prevent sweating on the suc ...Daha fazlası

Estimation of annual energy production of coupled vertical-axis wind turbines in a semi-complex terrain Eşli çalışan düşey eksenli rüzgar türbinlerinin yarı karmaşık bir sahadaki yıllık enerji üretiminin değerlendirilmesi

Başer, Ferhat Cem Ferhat Cem

ABSTRACTRecent research shows that the vertical-axis wind turbines (VAWTs) can provide up to 6 - 9 times more power generation in the same footprint area when they are sited in proper configurations in contrast to horizontal-axis wind turbines (HAWT). In order to site wind turbines in a field, it is necessary to do a wind resource assessment (WRA). This assessment provide important inputs for the placement, sizing and design detailing of the wind farm. In addition to the correct determination of the site, it is also critical to place the wind turbines in the most efficient way. When the necess ...Daha fazlası
