✦ Synopsis

In this study a turbulent combustion model for premixed flames with finite rate chemistry is implemented with a new calculation of the diffusion fluxes and turbulent kinetic energy taking into account the fluctuations of density. After the proposal of closure assumptions related to this phenomenon, the model is integrated and the results compared with a simple experimental study.

This experimental study concerns an oblique plane premixed (hydrogen-air) flame expanding in a turbulent confined flow. Measurements of mean and turbulent velocity field ate made using an LDV technique. For mean temperature and concentration measurements, a thermocouple and an isokinetic sampling probe, respectively, are used.

A quautum-chemical calculation has been made for some complexes of cadmium atoms with ethylenediamine and ammonia by using relativistic e&be core potentials. Calculated results show that the luminescences from the two-coordinate or cyclic exciplexes correspond to wavelengths longer than those from t

Particle transport velocities have been determined from published data for aqueous suspensions and dimensionless particle relaxation times (ti) ranging from 10m4 to 5. These were compared to predictions from several theories of particle transport. There is reasonably good agreement between measured

The flexural-free vibration of a cantilevered beam with multiple cross-section steps is investigated theoretically and experimentally. Experimental results are compared against Euler-Bernoulli beam theory solutions from Rayleigh-Ritz and component modal analyses, as well as finite element results us
