In this paper the thermal behavior of the shell-side flow of a shell-and-tufe heat exchanger has been studied using theoretical and experimental methods. The experimental method Provided the effect of the major parameters of the shell-side flow on thermal energy exchange. In the numerical method, besides the effect of the major paramerers, the effect of different geometric parameters and Re on ...

An experimental study of heat transfer characteristics with and without insert was found using water –water system on 1-2 pass shell and tube heat exchanger. Experimental results such as exchanger effectiveness, overall heat transfer coefficient were calculated using with and without insert. There is improvement in overall heat coefficient, efficiency in using twisted tape. In all the process i...

in this paper by the introduction of the basic equipment of a solar cooling system, solar hydrogen ammonia refrigeration system as a solar cooling technique will be discussed. using heat collector and absorption refrigeration allows us to use residual heat, for cooling, heating and producing hot water and boiling water .this research focuses on methods of heat transfer from the sun into the gen...

The performance of the adsorption cooling system is assessed in terms of the heat transfer coefficients of adsorbent bed heat exchanger. These parameters in-turn determine the specific cooling capacity (SCC) and the coefficient of the performance (COP) of the adsorption cooling system. It was observed that the overall heat transfer coefficients of the heat exchanger have a direct linear relatio...

the objective of the present study is the synthesis of mwcnt-tio2 hybrid nanostructures by solvothermal synthesis method with ticl4 as precursor. the heat transfer enhancement due to the use of mwcnt-tio2 nanofluid was investigated. as-prepared hybrid materials were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). the results showed that mwcnts were uniformly dec...

The reduction of SO2 and PM for marine engines was investigated using the electrostatic precipitator (ESP) with the heat exchanger. The experiments were carried out to reduce SO2 due to condensation of water in the exhausted gas. The experimental system consists of the diesel engine, the heat exchanger and the ESP. The exhausted gas at 180 o C of the temperature is cooled to 20 o C, and generat...

joule-thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields. in the current study, an attempt was made to indicate the effect of using inappropriate operational conditions in a cryogenic joule-thomson cooling system...

Energy saving is major matter in our global world, and heat exchanger is very useful for energy saving. Of course heat exchanger is most significant component for chemical reaction, distillation, dissolution, crystallization, fermentation etc. So the correct selection of heat exchanger is important in these processes. Spiral tube Heat Exchangers are known as excellent heat exchanger because of ...

By increase in the power of computer systems and enhanced power of the components and their temperature, including the central processing unit (CPU), cooling just by the air is not effective and there is need for more powerful systems to cool down and increase the power of the cooling system. In this article simulation of the heat exchanger material of the fluid cooling system has been studied ...
