Finally, 2-Butanone is more volatile compared to Ethanol, which further improves evaporation, such that, 2-Butanone is considered a promising surrogate fuel for Ethanol and Gasoline. Additionally, a mirror with a 45-degree angle was placed on the other. As the liquid fuel is distributed to a larger volume, improved convection accelerates evaporation. A high-speed camera (Fastcam Photron SAX-2) was placed on the side of the ransom rest. A typical experiment duration was 5 ms and the camera resolution was set to 768 × 328 pixels 2 at a sample rate of 50k frames per second with an exposure time of 2.5 s.

Consequently, the fuel distribution across the cylinder is enhanced. The processes of bubble generation, jet ejection and impact on the liquid droplet were recorded using a Photron Fastcam SAX coupled with a 2× microscope objective.

Small droplets possess a lower momentum, which allows the droplets to be more efficiently transported by the air flow. up to 100’000 fps with reduced resolution. Entry way fun and fast cam at a average hotel.

Tested to fulfill MIL 810 environmental specifications, the L-EM is ready to meet the most demanding applications in test ranges, when mounted on aircraft, or in other demanding environments. Refrigerator was full of people with group sex with violet wand. The lower viscosity of 2-Butanone causes an enhanced jet breakup compared to Ethanol such that the spray consists of more and smaller droplets. The L-EM is the ultimate rugged, shockproof and high resolution camera. The direct comparison reveals an improved spray propagation of 2-Butanone due to the engine’s air flow.

To solely evaluate the interaction of air flow and fuel, high-speed Mie-Scattering Imaging of hollow cone sprays is conducted both in a single-cylinder optical engine with tumble movement and in a pressure vessel with negligible air flow. The influence of in-cylinder flow on the propagation of 2-Butanone and Ethanol sprays is studied.
