Turbulent fixed-volume combustion bomb can create a turbulent environment, which can be used to study the pre-mixed flame combustion, oil spray combustion and other experiments, real-time monitoring and observation of the experimental process, support for data collection and product analysis.

 I. New breakthrough in the integration of industry, academia and research: project background and strategic significance

 A few days ago, the customized turbulent fixed volume combustion bomb independently developed by DianShi Instruments was successfully delivered to a university in central China, marking the upgrading of cooperation between the two sides in the field of engineering thermophysics research equipment.

 The implementation of this project will effectively support the related research in the field of energy power, and provide important technical support for the university's core technology breakthrough in the related fields.

II effective docking advantage: DianShi customization and precise empowerment

 Based on the special technical requirements of the project, the university selected DianShi Instruments as its partner after strict screening. Cooperation is mainly based on:

 (1) Technology accumulation: DianShi Instruments has rich experience in the research and development of combustion pyrolysis equipment, and has obtained nearly 40 relevant patents;

 (2) Customization ability: DianShi Instruments has successfully provided customized fixed-volume combustion bomb experimental devices for BYD, Southwest University, Northern China University and other head customers;

 (3) Service system: DianShi Instruments has a complete service chain from program design to after-sales training, with an internal pre-acceptance rate of 100%;

 (4) Product Matrix: DianShi Instruments has 5 series of fixed-volume incendiary bombs (spherical/cylindrical/high-temperature/turbulent/explosive-limit) of modular design, which can be accurately adapted to the needs of different experimental scenarios.

 According to the needs of the university in Central China, DianShi Instruments has custom designed a 15L fixed-volume combustion bomb experimental equipment. 15L fixed-volume combustion bomb has high-pressure, high-temperature, multi-group atmosphere, arc ignition, turbulence can create a variety of experimental environments of combustion test equipment. This fixed-volume combustion bomb needs to have the ability to ignite and burn materials in the chamber, create a turbulent atmosphere, and provide an environment for the analysis of gas products after combustion.

III Innovative technology: the core advantages of the turbulent fixed-volume combustion bomb

 The customized equipment delivered has a number of technical advantages:

 - Turbulent environment simulation: 15L fixed-volume combustion bomb experimental equipment chamber equipped with a fan can create a turbulent environment, the chamber is heated by heating wire heating can create a different ambient temperature, can simulate a certain high-temperature atmosphere, high-pressure atmosphere, turbulent atmosphere;

 - Atmosphere environment simulation: the use of electric spark ignition, the cavity is equipped with five-way air intake, can simulate different atmosphere environment;

 - Visualized observation and monitoring: Equipped with several Φ60mm observation windows to record the combustion process;

 - Intelligent analysis module: the whole chamber is equipped with pressure sensors and thermocouples for collecting and analyzing data. It makes the experimental environment more suitable for the experimental needs, the test data more accurate and the analysis more convenient;

 - Precise customization according to needs: Based on the process monitoring and alarm, and control system and other auxiliary solutions required by this fixed-volume combustion bomb, DianShi can provide solutions according to customer needs.

 Technical specifications:

 ●High-pressure environment: Maximum working pressure: 10MPa

 ●Vacuum environment: ultimate vacuum: 10Pa (A), vacuum time: ≤5min (1KPa)

 ●Product analysis: on-line analysis of O2, CO, CO2, SO2, NH3, CH4, C2H4, H2, etc.; Based on standards: ASTM E918, ASTM E2079, EN1839, EN15967, UL9540A

IV Mature cooperation paradigm

 This cooperation marks a new breakthrough in the field of non-standard experimental equipment. The successful landing of the project not only provides hardware support for the technical research of the cooperating universities, but also further promotes the new industry-university-research cooperation paradigm of "universities make the problem - enterprises solve the problem - and jointly attack the problem" towards regularization and maturity.

 With the official launch of the turbulent fixed-volume combustion bomb, it is expected that the cooperating universities will produce influential scientific research results in the future, which will contribute to the construction of a strong scientific and technological country in the field of engineering thermophysics.
