The objective of this paper is to study the effect nanofluid on performance heat exchanger, as well transfer rate, coefficient total transfer, friction influence and average Nusselt number, thermal efficiency factor has been investigated discussed. In work, output Fe3O4/water through shell tube exchanger numerically under laminar flow. CFD simulations with ANSYS FLUENT 2020R1 were used adopting...

The purpose of the article is to improve strength calculation tube plate shell-and-tube heat exchanger, which regulated by interstate standard in force Ukraine. On basis tables, dot plots change coefficients were constructed and analyzed, take into account supporting effect pipes Ф1, Ф2, Ф3 depending on dimensionless parameter board-pipe system ω dependence stiffness coefficient perforated boar...

The aim of this study is to present a short but comprehensive presentation the strength dimensioning one most common chemical equipment, heat exchanger, in particular shell-and-tube type. This equipment classified as pressure vessel, which means all aspects design, manufacture and investigation are subject standard specifications. As these exchangers essential for industry related technologies,...

The single-phase flow and thermal performance of a double pipe heat exchanger are examined by experimental methods. The working fluid is water at atmospheric pressure. Temperature measurements at the inlet and outlet of the two streams and also at an intermediate point half way between the inlet and outlet is made, using copper-constantan thermocouple wires. Mass flow rates for each stream are ...

The solidification process in a multi-tube latent heat energy system is affected by the natural convection and arrangement of exchanger tubes, which changes buoyancy effect as well. In current work, tubes was examined during with focus on effects inside phase change material (PCM). behavior numerically analyzed using liquid fraction released, well temperature, velocity streamline profiles for d...

Shell-and-tube heat exchangers are widely used in many research fields and industrial production processes, but little has been conducted on the use of for drying crops. This study a numerical simulation temperature, velocity, pressure based shell-and-tube fluids exchanger biomass particle hot-blast stove. The correctness results was verified by test data before simulation, mesh to be irrelevan...

Hampir seluruh proses produksi dan aktifitas manusia berhubungan dengan energi. Dengan meningkatnya kebutuhan energi maka diperlukan suatu usaha untuk melakukan efisiensi pada tersebut. Heat exchanger adalah alat yang digunakan dalam perpindahan panas fluida lain tanpa terjadi massa dapat dipergunakan sebagai pemanas maupun pendingin. Salah satu jenis heat sering di industri shell and tube exch...

For many countries, increasing energy efficiency and reducing greenhouse gas emissions are key countermeasures to cope with the energy crisis and climate change. Of the various heating equipment such as heat pumps, gas-fired boilers, oil-fired boilers, or electric boilers, heat pumps are widely adopted for space heating, water heating, and process heating by households, business, and industry d...

This paper presents how the thermal performance of an existing finned-tube heat exchanger is determined experimentally. In the experiment, heat is transferred from an exhaust gas stream to a thermal oil. The experimental setup is discussed including the thermal fluid selection process, the components, instrumentation and resultant measurement uncertainty. The heat transfer is calculated individ...
