Cu-H2O nanofluid intercooler for cooling exhaust gas of shipborne gas turbine gas compressor

Abstract

The invention discloses a Cu-H2O nanofluid intercooler applied to a shipborne gas turbine to cool the exhaust gas of a shipborne gas turbine gas compressor, and belongs to the technical field of nanofluids and enhanced heat transfer. The nanofluid intercooler is characterized in that the nanofluid intercooler is mainly composed of a nanofluid preparation device, a power device meeting fluid flowing and a plate-fin heat exchanger. When a liquid pump works, impellers are driven to rotate, and a mechanical stirring effect is also achieved on the nanofluid on the basis of driving the nanofluid toflow.

Description

technical field [0001] The invention relates to a nano-fluid intercooler applied to a ship-borne gas turbine, belonging to the technical field of nano-fluid and enhanced heat transfer. It is characterized in that the nano-fluid intercooler is mainly composed of a nano-fluid preparation device, a power device satisfying fluid flow and a plate-fin heat exchanger. When the liquid pump works, it drives the impeller to rotate, and on the basis of driving the flow of the nano-fluid, it also forms a mechanical stirring effect on the nano-fluid. Background technique [0002] In recent years, the country's demand for large ships has been increasing day by day, and large ships need high-power engines to drive. But the existing engines can't fully meet the needs, especially some large ships with high mobility requirements. Therefore, such ships are generally driven by gas turbines, which is determined by the characteristics of the gas turbine itself. At present, there are two main i...

Problems solved by technology

However, when the traditional pure liquid heat exchange working medium is applied to the intercooler, due to its low-quality heat exchange capacity, the structure of the heat exchange equipment is often too large, which can no longer meet the current energy saving, environmental protection, high efficiency, equipment integration, and miniaturization. Development needs, and the superior performance of nanofluids in enhancing heat transfer has been confirmed by experiments by many contemporary experts and scholars

However, due to the difficulty of preparing nanofluids and the stability of suspension in practical applications, they cannot be effectively solved, so there is no ship-mounted gas turbine intercooler equipment that effectively combines the advantages of the two.
