ABSTRACTEnvironment and health is two important things that are so important to human lifebecause they cannot be separated from each other. The problems related with thesetwo events will negatively affect human life. Therefore, health and environmentalproblems should be monitored with proper testing devices and analyzed. In order toperform these tests, we need cheap, reliable and fast test equipment. With therevolution of three-dimensional (3D) printing technology that is cheap, practical, fastmethod of production, this kind of test devices can be produced. This productionmethod is used to pro ...Daha fazlası

Manufacturing and characterization of thermal conductive polymeric composite materials Termal iletken polimerik kompozit malzemelerin üretilmesi ve karekterizasyonu

Kaya, Nusret

ABSTRACTElectronic industry is growing dramatically in the last quarter of the century. Recent advances in electronics industry enable the miniaturization of micro transistors and the integration of more transistors into the electronic devices, resulting in a higher performance device. However, this condition increases the heat flow in the electronic devices. The performance of electronic devices depend on the working temperature, for this reason, it is important to remove the heat produced in the device as fast and efficiently as possible in order to hold the system temperature of the electro ...Daha fazlası

Modeling and experimental study of turbulent newtonian fluid in fully eccentric annulus considering temperature and pipe rotation effects

In this work, the effect of temperature on the pressure loss of Newtonian fluid in a fully eccentric annulus with pipe rotation is investigated. For this purpose, initially comprehensive experimental study has been conducted at Izmir Katip Celebi University (IKCU), Fluid Mechanics and Hydraulics Laboratory of Civil Engineering Department. Effect of temperature has been observed for flow velocities from 0.7 m/s to 3.4 m/s, for pipe rotations from 0 rpm to 120 rpm, and for temperatures is from 20 °C to 65 °C. The pressure loss within the test section is recorded. An increase in the liquid temper ...Daha fazlası

Nanocomposites with graphene

The carbon fiber used in the manufacturing of advanced composites has various applications in the automotive, aerospace, and electronics industry because of their comprehensive properties such as lightweight, flexibility, high strength to weight ratio, excellent chemical resistance, superior electrical conductivity and thermal conductivity. Different kinds of carbon fiber precursors have been used and polyacrylonitrile (PAN) is the mostly utilized polymer type which is a petroleum-based, expensive and unsustainable. Remarkably, lignin is a highly accessible, low-cost, and renewable resource. ...Daha fazlası
