In this paper, the rate of heat transfer by forced convection in a counterflow exchanger, at turbulent flow conditions were investigated experimentally, using porous media and TiO2 Nanofluid to observe behaviour with volume concentration nanoparticles t enhance through it. 3 mm Steel balls (ε=39.12%) as completely filled inner pipe (core pipe). The cold hot water are used working fluids outer p...

The present paper discusses the pressure loss through the spiral heat exchanger (HX) proposed in the ELSY (European-Lead cooled SYstem) project. An approach based on CFD (Computational Fluid Dynamics) using the commercial code ANSYS CFX has been used for exploring the flow through the HX. The HX consists of perforated double inner and double outer walls, as well as an innovative spiral design o...

Teknologi penukar panas sekarang ini telah diaplikasikan pada berbagai bidang teknologi. Salah satunya teknologi otomotif khususnya radiator. satu contoh untuk meningkatkan konduktivitas termal fluida adalah dengan merekayasa pendingan. Coolant cairan pendingin yang berbahan dasar etilen glikol digunakan mengurangi atau mengatur suhu suatu sistem. Pada penelitian dilakukan percobaan menggunakan...

Generally, Central Asia is typical for regions with strong solar radiation and various natural cooling sources. The heat gain from the building envelope accounts for a large part of the cooling load there. Thus, the pipe-embedded envelope is receiving attention as a semi-active system of utilizing natural energy for cooling. In this study, the performance of the pipe-embedded envelope used in U...

The need for energy and material savings, as well environmental concerns, have helped to increase the demand high-efficiency heat exchangers in modern era. In practice, a exchanger or direct ejection of hot working fluid is used recover waste from engine thermal power plant into environment. Waste recovered environment via by fluid. many situations, recovery removes greatly reduces necessity ad...
