NettetThis is why dynamic pressure calibration methods should be developed. The present author does not know the percentage of pressure measurements that are performed with the intention to capture dynamic phenomena. It is quite clear, however, that the lack of traceability for dynamic pressure measurements in industry results in less- NettetLinek, V., Benes, P. and Sinkule, J.

NettetThe dynamic pressure method developed by our research group is based on a steep change of the pressure above the bubbled vessel causing imminent change of the tracer gas (oxygen) partial pressure in all bubbles in the batch avoiding the complications mentioned above. Linek, V.; Benes, P.; Vacek, V., 1989. Nettet3. mar. 2024 · For the experimental determination of k L a, various methods (dynamic pressure method, steady-state sulfite method, and others) have been developed in the course of years. After testing, 7 − 9 the dynamic pressure method, DPM, has been established as the best method, which can even measure high k L a values correctly.
NettetThe dynamic pressure method (DPM) is used for measurement of k L a in a 1‐m 3 pilot scale fermentor in coalescing (distilled water) and noncoalescing (0.3 M Na 2 SO 4 aqueous solution) batches. The method consists in recording oxygen concentration in a batch after a small pressure change (20 kPa) in the fermentor.
