Monitoring of n-butanol vapors biofiltration process using an electronic nose combined with calibration models
PublicationMalodours, by definition, are generally unpleasant, nuisance smells that are a mixture of volatile chemical compounds which can be perceptible even at low concentrations. Due to the more frequent occurrence of odour nuisance associated with the odour sensations, and thus the need to remove them from the air, deodorization techniques are commonly used. Biofiltration is one of the methods of reducing odorants in the air stream. In...

Dostosowanie parametrów modelu procesu do warunków badań symulacyjnych, na przykładzie napędu pneumatycznego
PublicationNiekiedy parametry opisujące właściwości procesu czy elementu wyznaczane są eksperymentalnie (przykładowo: współczynniki tarcia par kinematycznych, współczynnik wymiarowy zaworu Kv). Często procedury ich wyznaczania objęte są normami bądź opisanymi w literaturze i szeroko stosowanymi metodykami. Nie zawsze jednak modele matematyczne wykorzystywane do wyznaczania wartości parametrów opisujących właściwości mogą być wykorzystane...
