Improving performance of transcritical CO2 systems, using phase change materials (PCM) in a cold storage application
(International Institute of Refrigeration, 2019)
Thermal energy storage is one of the most promising solutions for energy savings and increasing efficiency. To improve the performance of cold storage applications, incorporating phase change materials (PCM) to these ...
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 ...
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 ...
The performance evaluation of CO2 transcritical booster and R290/R744 cascade refrigeration systems for different cities in Turkey
(International Institute of Refrigeration, 2017)
CO2 as a natural and fully environmentally friendly refrigerant has become more preferable in refrigeration systems in recent years. Since its critical temperature is much lower than that of other refrigerants. It is mostly ...
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 ...
The place of pedagogical training in engineering education
(2014)
Academic personnel attendant in engineering education predominantly performs educational functions besides research functions, development and laboratory works. At this stage, the communication and interaction between ...
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 ...
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 ...
