Compressible Flow of Fluids Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14183

Overview

The Compressible Flow of Fluids Apparatus is designed to study the principles of airflow in compressible regimes, covering both subsonic and transonic velocity ranges. The setup allows users to observe and measure how pressure, velocity, and density interrelate when the air velocity approaches or exceeds the speed of sound (Mach 1).

This trainer provides an in-depth understanding of flow phenomena critical to the design of jet engines, turbines, compressors, and supersonic aircraft. A de Laval nozzle within the system enables the generation of transonic flow conditions, while transparent measuring sections allow direct visualization of airflow behavior and pressure distribution.

All test sections and components are arranged to minimize turbulence, ensuring high-quality data and accurate analysis. The apparatus includes digital instrumentation and optional data acquisition software for real-time monitoring and recording of flow parameters. A comprehensive Operation & Maintenance Manual is provided.
