Stokes Generation

A semiclassical theoretical model of a Raman laser possessing a cavity which is resonant at the Stokes wavelength and not resonant at the pump wavelength has been developed. The wave equations describing evolution of amplitudes of the pump and Stokes pulses in the Raman cavity have been derived. Results of the theoretical modeling have been analyzed for conditions of an experiment with the Raman laser on barium nitrate crystal under the nanosecond pulse pump. Numerically calculated energy characteristics of the Raman laser as well as space-time dynamics of the Stokes generation have been demonstrated to be in reasonable agreement with the experiment.

Theoretical Results

Theoretical model has been formulated of the flow of liquid in a randomly packed trickle bed column equipped with special wall flow deflecting rings (WFDR). Solutions have been obtained of the model for the case of a single ring. Theoretical results have been compared with experimental distributions of liquid in a 188.6 mm in diameter column packed with 25 mm Raschig rings and equipped with a single WFDR. Reasonable agreement of the theory with experimental results has been found and the theory is felt to be important in the future for optimizations of the number, size and spacing of the WFDR's to be used in industrial columns to check the extent of the flow on the wall.

Significant Element

A theoretical model for predicting noise reduction in coupled workshops is presented by using statistical energy analysis (SEA) method. An opening between the coupled workshops is considered into the theoretical model properly. The leakage issue is dealt with in the process of SEA modeling. An experiment is also carried out. A reasonable agreement between the prediction of noise reduction and the experimental data is observed. Moreover, it is concluded from the simulations that the sound energy transmit through the opening was the most important way to affect the noise reduction and the leakage is a significant element to influence the effect of noise treatment.
