Different types of plate heat exchanger: Plate-and-frame heat exchangers, gasketed plate heat exchangers, spiral plate heat exchangers, lamella heat exchangers, panel coil heat exchangers [24].
We have just celebrated the 125th anniversary of Thomas Edison's success in heating a spiral of carbonized cotton thread to incandescence for 14 hours in his lab in New Jersey.
Studies that have been performed on the heat transfer of spiral heat exchanger have focused on field measurements and numerical analysis; however, theoretical research on the subject is absent in the literature.
The chamber had penetrations for a copper spiral water-heating coil, infusion pump, pressure transducer, temperature sensors, and electric cables, as well as breathing gas supply and exhaust.
A single accident, a single shutdown can send prices of gasoline and heating oil spiraling all over the country.
In this study, a methodology is proposed to analyze the heat performance of a spiral heat exchanger.
In order to explore the shell-side heat transfer characteristic for spiral wound heat exchanger (SWHE) in floating liquefied natural gas (FLNG) field, a model was established to simulate the heat transfer of shell-side film flow in real working conditions.
In order to explore the shell-side flow and heat transfer characteristics for spiral wound heat exchanger (SWHE) in floating liquefied natural gas (FLNG), a model was established to simulate the flow and heat transfer of shell-side superheated vapor flow under rolling working conditions.
All scales were identified by X-ray diffractometer to be aragonite, but in the case of magnetic treatment, scales occurred in much smaller amounts: the scale on heating copper-pipe spiral was 2.5-times thinner due to MWT and in zinc-coated steel pipe occurred as very thin powder-like coating, while in the line without the treatment abundant hard lining was formed.
This paper presents a new transient analytical model for describing the heat transfer process of pile geothermal heat exchangers with spiral coils (PGHE-SC).
