摘要

本文对二元离子液体混合物非线性声学参数的计算进行了研究，这是非线性声学研究的一个重要领域。本文首次采用Hartmann、Ballou、Johnson和Sharma的热声方法计算了六种二元离子液体混合物的非线性声学参数（B/A）。在298.15 K下，6种RTIL的二元混合物为DEAA +水、DEAS +水、TEAA +水、TEAS +水、TMAA +水和TMAS +水。密度（ρ）和声速(u)的实验输入数据取自Venbatesu等人非常精确的工作（J Phys Chem 13:18, 2014）。5971)。对不同方法得到的（B/A）值进行了比较研究。

Computation of Beyer’s Nonlinearity Acoustic Parameter of Binary Ionic Liquids (RTIL’s) Mixtures

This study focuses on the computation of the nonlinearity acoustic parameter for binary ionic liquid mixtures, which is an important area of research in nonlinear acoustics. For the first time nonlinear acoustic parameter (B/A) of six binary ionic liquid mixture have been computed using four different methods namely Hartmann, Ballou, Johnson and thermoacoustic method of Sharma. The binary mixtures of six RTIL’s are DEAA + water, DEAS + water, TEAA + water, TEAS + water, TMAA + water and TMAS + water at 298.15 K. The experimental input data of density (ρ) and sound speed (u) have been taken from a very accurate and precise work of Venbatesu et al. (J Phys Chem 13:118, 2014. 5971). A comparative study of (B/A) values obtained from different methods has been presented.
