This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A non-intrusive laser diagnostics technique has been developed for simultaneous measurements of velocity and gas temperature in optically accessible internal combustion en-gines. The technique, thermographic PIV (T-PIV) combines phosphor thermometry and particle image velocimetry (PIV) and offers the possibility of simultaneous measurement of gas temperature and velocity.Suitable phosphor materials were selected by testing three commercially available phosphors: BAM:Eu2+, ZnO and ZnO:Zn. The lumines-cence emission and the spectral response to var-ious parameters including temperature were measured yielding a temperature-dependent cal-ibration curve to be used for signal interpreta-tion in engine experiments. The ZnO:Zn phos-phor shows the highest sensitivity to tempera-ture allowing higher temperature precision. Therefore, ZnO:Zn phosphor was chosen as the suitable candidate for engine measurements.Measurements were performed in an internal combustion engine at a speed of 1200 rpm with a sampling rate of 10 Hz between 180 and 540°CA under motored conditions. The temper-ature and velocity fields were measured success-fully at various times throughout the compres-sion and the exhaust stroke. The obtained tem-perature fields are compared with simulated bulk-gas temperatures from a 0D model-based simulation showing a temperature deviation of around 1% (200°CA) to 14% (480°CA) from the model. The measurement accuracy was found to be 55 K (18%) at 300 K and 2 K (0.3%) at 614 K for the 200-cycles average.The potential of the diagnostics was tested also in in cylinder post-combustion gases. In this case, the diagnostics was failing probably due to the characteristics of the phosphor used, which does not seem to resist to high combustion tem-peratures degrading its luminescence properties. The potential of T-PIV in post-combustion gases remains under the conditions of finding more resistant phosphor particles.

This book was released on 1989 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development and the design of advanced hypersonic vehicles such as the National Aerospace Plane (NASP) or the Space Shuttle will strongly depend on computer simulation mainly because some of the flight conditions experienced by these vehicles will be difficult or prohibitively expensive to create in ground facilities. Computer simulation will be used to reduce the need for expensive test time or will replace those experimental tests which can not be performed. However, computer simulations require validation before their results can be accepted. These validation tests, which must be performed in hypersonic and turbulent air flows, require the simultaneous measurement of air temperature, density and velocity at a high temporal and spatial resolution which will allow to resolve turbulence structures.
