The hydrodynamic characteristics of mixing fluids are always the points to consider in improvement their quality especially using motionless mixers normally stated as “Static Mixers”. Motionless technique was adopted for Air-Water system with advantage negligible power consumption over dynamic mixers. Different were experimented “Baffle Type” static element and compared those already used recen...

A predictive long short-term memory (LSTM) model developed on a particular water quality dataset will only apply to the and may fail make an accurate prediction another dataset. This paper focuses improving LSTM tolerance by mitigating discrepancies in capability that arises when is applied different datasets. Two models are from datasets, Baffle Burnett, optimised using metaheuristic genetic a...

Abstract Sloshing is relevant in several applications like ship tanks, space and automotive industry seiching harbours. Due to the relationship between sloshing motions possibility of structural damage, it important represent this phenomenon accurately. This paper investigates at shallow liquid depths a rectangular container using experiments RANS simulations. Free forced sloshing, with without...

Engine noise, as a source of sound pollution for humans and the environment, can be reduced by designing high-performance muffler. This study presents novel, organized design process that muffler KTM390 engine case study. The acoustic simulation analysis is performed in COMSOL software aerodynamic ANSYS Fluent. features considered this are overall length muffler, presence baffles related parame...

Spherical harmonic (SH) representations of sound fields are usually obtained from microphone arrays with rigid spherical baffles whereby the microphones distributed over entire surface baffle. We present a method that overcomes requirement for baffle to be spherical. Furthermore, can placed along circumferential contour around This greatly reduces required number given spatial resolution compar...

The problem of the rigid-piston radiator mounted in an infinite baffle has been studied widely for tutorial as well as for practical reasons. The resulting theory is commonly applied to model a loudspeaker in the audio-frequency range. A special function, the Struve function H1 (z), occurs in the expressions for the rigid-piston radiator. This Struve function is not readily available in program...
