Product Description
This product is designed for theoretical analysis and experimental research related to gas flow and nozzle calculations in Engineering Thermodynamics and Aerodynamics.
The system consists of a gas source, test section, pressure measurement unit, and control valve assembly. By coordinating the air pump and valves, the apparatus can measure the pressure distribution curves of both converging nozzles and converging–diverging nozzles (Laval nozzles). The inlet pressure and back pressure of the nozzle can both be adjusted.
Three interchangeable nozzles are provided for studying the relationship between pressure and velocity ratios in different nozzle configurations, including one converging nozzle profile and two Laval nozzles with different expansion section lengths. The system is compact, safe, and suitable for independent laboratory experiments.
Experimental Functions
1
Demonstrate the nozzle choking phenomenon.
2
Study flow phenomena such as overexpansion and underexpansion when shock waves occur in the nozzle.
3
Investigate the relationship between inlet pressure and flow velocity inside the nozzle.
4
Study the relationship between ambient back pressure and internal flow velocity.
5
Analyze the influence of inlet pressure and back pressure on nozzle flow velocity.
6
Study the pressure distribution inside three types of nozzles under different inlet-to-outlet pressure ratios.
7
Support additional extended nozzle designs and experiments.

FAQ
Is your company a manufacturer or a trading company?
We are a direct source manufacturer with independent R&D, production and quality inspection workshops, and have years of expertise in the university laboratory equipment sector.
What payment methods are supported for overseas orders?
We accept T/T (Telegraphic Transfer) and irrevocable sight L/C (Letter of Credit). Formal commercial or proforma invoices are issued for all orders, with a transparent and traceable process.
What is the production and delivery cycle for the equipment?
Standard models: 45-60 days. Expedited production is available for urgent orders with priority scheduling, and the exact lead time is negotiable.
Do you support product customization?
Customization, OEM and ODM services are available. We can adjust parameters, structure, size and functions as required, and accept private labeling production.
How do you ensure the safe transport of the equipment?
Export-grade triple shockproof and moisture-proof packaging (shockproof foam + thickened carton + plywood wooden case) with warning labels attached.
Does the product come with a warranty? Are spare parts included?
All products come with a 2-year free original factory warranty, and common wearing parts are provided free of charge during the warranty period.
Overseas After-Sales Support：
• 7×24h remote technical support and free operation training with one-on-one engineer guidance;
• Free urgent air shipment of replacement parts for non-human-induced quality defects within the warranty period;
• Lifetime technical consultation and cost-price spare parts supply after warranty;
• Bilingual manuals, operation videos and experiment guides are included for easy use by beginners.
How do you control product quality before shipment?
Strict three-level quality inspection is carried out before delivery:
1. Raw Material Inspection: Full inspection of core components to control precision;
2. In-Process Inspection: Special personnel monitor each process to avoid defects;
3. Final Shipment Inspection: Power-on testing and precision calibration, with official inspection reports issued; factory inspection and remote inspection are both supported.
