	abstract = {This research deals with pressure waves in a gas trapped in thin layers or narrow tubes. In these cases viscous and thermal effects can have a significant effect on the propagation of waves. This so-called viscothermal wave propagation is governed by a number of dimensionless parameters. The two most important parameters are the shear wave number and the reduced frequency. These parameters were used to put into perspective the models that were presented in the literature. The analysis shows that the complete parameter range is covered by three classes of models: the standard wave equation model, the low reduced frequency model and the full linearized Navier-Stokes model. For the majority of practical situations, the low reduced frequency model is sufficient and the most efficient to describe viscothermal wave propagation. The full linearized Navier-Stokes model should only be used under extreme conditions.},

	abstract = {Viscothermal acoustics can be described by the linearized Navier Stokes equations. Besides inertia and compressibility, these equations take the heat conductivity and the viscosity of the medium (air) into account. These 'viscothermal' effects are significant in, for example, miniature acoustic transducers and {MEMS} devices. A finite element for viscothermal acoustics, which can be used to model such devices, is presented. The particular set of equations used in the model of viscothermal acoustics leads to a complex symmetric finite element system matrix. Several different {FEM} discretizations are studied on a 2D thin gap problem. These discretizations are known, in the context of the Stokes equation, as the Taylor Hood quadrilateral and triangle elements, the Crouzeix Raviart element and the {MINI} element. All elements are implemented in the {FEM} software {COMSOL}. The elements with quadratic velocity and temperature shape functions show the best orders of convergence.},

	doi = {10.1016/S0022-460X(75)80206-9},
	abstract = {It is shown that the two main parameters governing the propagation of sound waves in gases contained in rigid cylindrical tubes, are the shear wave number, s = R ρ s ω / μ , and the reduced frequency, k=ωR/a0. It appears possible to rewrite the most significant analytical solutions for the propagation constant, Γ, as given in the literature, as simple expressions in terms of these two parameters. With the aid of these expressions the various solutions are put in perspective and their ranges of applicability are indicated.

It is demonstrated that most of the analytical solutions are dependent only on the shear wave number, s, and that they are covered completely by the solution obtained for the first time by Zwikker and Kosten (1949).

The full solution of the problem has been obtained by Kirchhoff (1868) in the form of a complicated, complex transcendental equation. In the present paper this equation is rewritten in terms of the mentioned basic parameters and brought in the attractive form F\&lt;, s, k\&gt;=0, which is solved numerically by using the Newton-Raphson procedure. As first estimate in this procedure the value ofaccording to the solution of Zwikker and Kosten is taken. Results are presented for a wide range of s and k values.},

These viscothermal effects can be important, for example in models of small acoustic transducers. Viscothermal acoustics can be modeled in arbitrary geometries with models that contain four or five coupled fields. Therefore, these fully coupled models are computationally costly. On the other hand, efficient approximate viscothermal acoustic models exist, but these are only applicable to certain simplified geometries. A new approximate model is presented which fills the gap between these two extremes. This new model can be used for arbitrary geometries and has a computational efficiency which is higher than the full model and lower than the models with geometrical constraints. The new model is derived and demonstrated on several problems, including acoustic-structure interaction problems.},

Existing boundary element or finite element acoustic software does not include these phenomena, as they are not compatible with the basic equations involved. A methodology is given to solve such problems when using this software, introducing a hybrid method which combines both numerical solutions and analytical solutions (for the fields inside the boundary layers).

	doi = {10.3813/AAA.918398},
	abstract = {When modeling acoustics with viscothermal effects included, typically of importance for narrow tubes and slits, one can often use the so-called low reduced frequency model. With this model a characteristic length is assumed for which the sound pressure is constant. For example for a circular cylindrical tube the characteristic length is the radius. A triangular cross-section does not have a characteristic length, but as will be shown in this paper the model can in fact be used as long as 1) the cross-sectional pressure is constant and 2) a characteristic impedance and propagation wavenumber can be established for the geometry. These parameters can be found for a tube with a triangular cross-section and an implementation of the low reduced frequency which can handle tubes with both circular, rectangular triangular cross-sections has been made in {COMSOL} Multiphysics. For the circular and the rectangular tube results found using this implementation have been compared to results from an analytical model, a so-called full Navier-Stokes implementation in {COMSOL} Multiphysics and the commercial package {FFT} {ACTRAN} which also uses the low reduced frequency model. The triangular tube implementation has been compared to the analytical case as well as the full Navier-Stokes implementation.},
