🔊 The Acoustics Module of the newly released COMSOL Multiphysics version 6.2 is out now! It is packed with new functionality that extends what can be simulated and simplifies the setup of models.
👋 In this version we introduce the tools to easily and automatically analyze and set up frequency dependent impedance conditions in the time domain. This is important in many applications, one of them is for wave-based room acoustic simulations (as in the animation, taken from a new tutorial model).
✈️ Port conditions are now available for the linearized potential flow formulation for modal source decomposition, typically used for the analysis of sound radiation from turbo-jet engine flow ducts.
🎙 A new slip wall formulation is available in thermoviscous acoustics, further extending the validity of the continuum formulation in MEMS devices. We have also introduced a surface tension feature in thermoviscous acoustics for modeling the vibration of microbubbles or free surfaces in inkjet system.

Great news! WavePro® is included in the latest release of COMSOL, Inc.’s material library, allowing designers to select our materials.
Pictured here: Enhanced gain of an aperture antenna achieved using a ceramic-filled PTFE dielectric lens made from WavePro® WP025LDf low-loss dielectric material. The computation for this conical horn antenna was expedited using the 2D axisymmetric formulation in COMSOL, Inc.'s Multiphysics® software.

RANS vs URANS vs DES turbulence modeling on NACA 0012 AOA25DEG Vorticity.
RANS stands for Reynolds-Averaged Navier-Stokes.
It is a method that averages the flow variables over time to obtain a mean flow field and then models the effect of turbulence using additional equations for the turbulent fluctuations.
RANS models are computationally efficient and widely used for industrial applications, but they have limitations in capturing complex flow features and unsteady phenomena.
URANS stands for Unsteady Reynolds-Averaged Navier-Stokes.
It is a method that solves the RANS equations in a time-dependent manner, allowing for some unsteady effects to be captured.
DES stands for Detached-Eddy Simulation.
It is a hybrid method that combines RANS and LES in different regions of the flow domain.
DES models are less costly than LES models, but they can suffer from numerical issues at the interface between RANS and LES zones.

Designing the Sound Absorption of Microlattice Structures
“As the capabilities and resolution of additive manufacturing technologies continue to improve, it will be possible to develop lightweight, lattice cell configurations with fine-enough microgeometries that offer optimal sound absorption properties across a very broad frequency range. [The] prospect of designing potential ‘virtual’ microgeometry design configurations using numerical simulation techniques and then printing them [...] is indeed very exciting.”
In this blog post, a guest author from KTH Sweden shares how acoustics modeling can be used to design microlattice structures with optimal sound absorption properties. Start reading here:

شبیهسازی فرآیند آبگیری هواپیمای آتشنشان
این هواپیماها نقش مهمی در مبارزه با آتشسوزی جنگلها و بلایای طبیعی دارند. توانایی آنها در ریختن 6 تن آب در مناطق آسیب دیده آنها را به متحدان ضروری تیمهای نجات تبدیل میکند.
یک مرحله ضروری در آمادهسازی Canadair CL-215 برای عملیات اطفای حریق، بارگیری آب است. هنگامی که یک نقطه آبی انتخاب شد، Canadair یک مانور فرود را انجام میدهد و روی سطح آب فرود میآید. به لطف سیستمهای اسکوپینگ پیشرفته، آب مکیده شده و در مخازن هواپیما ذخیره میشود.
طراحان هواپیما از CFD برای مدلسازی و شبیهسازی نحوه جذب، ذخیره و رها شدن آب در طول عملیات اطفاء حریق استفاده میکنند. این امر طراحی مخازن کارآمد و بهینهسازی سیستمهای اسکوپینگ و همچنین مطالعه فشار وارد شده توسط سازه در طول آبگیری را امکان پذیر میسازد.
قبل از اجرای عملیات واقعی ریزش آب، میتوانند ریزش آب از هواپیما را شبیهسازی کنند. این امر بسته به متغیرهایی مانند سرعت هواپیما، ارتفاع و شرایط آب و هوایی، پراکندگی در حین پرواز را پیشبینی میکند.
