Experimental and Numerical Analyses of A Heat Pump-Driven Chilled Ceiling Systems
(Begell House, 2018)
Passive cooling covers the natural processes of heat dissipation and heat gain operations and provides a highly efficient, comfortable environment around. As commonly known, when air is heated, it rises, when cooled, it ...
Ultra Düşük Sıcaklıklarda Çalışan İki Kademeli Bir Soğutma Sisteminde Aşırı Soğutma ve Isıtmanın Performansa Etkilerinin Sayısal İncelenmesi
(2017)
Soğutma sistemleri çalışılmak istenen soğutma sıcaklığına bağlı olarak çeşitli kategorilere ayrılmaktadır. -50°C ve -100°C sıcaklık aralığında gerçekleştirilen soğutma işlemleri ultra düşük sıcaklık uygulaması sınıfına ...
Alternative approach for the derivation of an eigenvalue problem for a Bernoulli-Euler beam carrying a single in-span elastic rod with a tip-mounted mass
(TECHNO-PRESS, 2015)
Many vibrating mechanical systems from the real life are modeled as combined dynamical systems consisting of beams to which spring-mass secondary systems are attached. In most of the publications on this topic, masses of ...
Damping properties of open pore aluminum foams produced by vacuum casting and nacl dissolution process
(Elsevier, 2013)
In this study,damping ratios of 3 samples made of aluminum foam material, which have different-density pores, were calculated, the effects pore density on damping were examined. Experimental modal analysis method was used ...
Gözenekli malzemelerin sönümlemeye etkisi
(Afyon Kocatepe Üniversitesi, 2011)
Gözenekli ve gözeneksiz malzemelerin titreşim büyüklüğü araştırılmıştır. Metalik köpükler kullanılmıştır. Köpük doğal bir ürün değildir. Kapalı ve açık hücreli metalik köpükler mevcuttur. Gözenekli malzemede sönümleme ...
Comparative Cost Assessment of Cold Storage Plants and Natural Storage Structures for Potato
(Springer, 2020)
The use of a cold storage plant for reducing perishable food losses is insufficient in developing and underdeveloped countries because of required infrastructure and investments. For this reason, many producers continue ...
Ultra Düşük Sıcaklıkta (-78 °C) Kaskad Soğutma Sisteminin Farklı Tasarım ve Operasyon Parametreleri İçin Teorik Analizi
(Tesisat Mühendisliği, 2021)
Ultra düşük sıcaklıkta çalışan soğutma sistemlerinin kullanım alanları oldukça yaygındır. Özellikle biyolojik ürünlerin uzun süre depolanabilmesi için ultra düşük sıcaklıklarda çalışabilen soğutma sistemlerine ihtiyaç ...
Optimization of the finned double-pipe heat exchanger using nanofluids as working fluids
(Springer, 2020)
The heat exchanger pipe diameter has a significant effect on the flow characteristics as well as on the initial investment, operation and overall cost. Increasing fin dimensions increases the annulus hydraulic diameters. ...
A Numerical Analysis of Convection Heat Transfer and Friction Factor for Oscillating Corrugated Channel Flows
(Taylor and Francis Ltd., 2021)
The aim of this article is to understand numerically the flow and heat transfer characteristics under oscillating flow conditions for periodically corrugated wavy channel. For the same channel, under steady-state flow ...
Experimental investigation of PCM location in a commercial display cabinet cooled by a transcritical CO2 system
(Elsevier, 2020)
In this study, the influence of phase change material (PCM) location in a closed display cabinet cooled by a transcritical CO2 refrigeration system was examined experimentally. Two configurations have been investigated ...
