    with good accuracy.

    Hi,

    Are the bold part of following sentences correct grammatically?

    *In other words, when wall function approach is used, viscosity-affected inner region (viscous sublayer and buffer layer) is computed by using semi-empirical formulas with good accuracy.


    Thanks.

    Re: with good accuracy.

    Your question is incorrect. Subject is part (singular) verb is are (plural). Your subject and verb should agree in number.

    You also need to understand better how to use articles (a, an, the). Your writing will improve if you start to use them.

    As to the part in bold: To my ear, good accuracy is redundant. Accuracy is always 'good' in scientific work. There's no such thing as 'bad' accuracy. We may, however, speak of a high degree of accuracy, but I'm not sure it would be appropriate here.

    I don't know what is meant by "semi-empirical formulas" in this situation. It's not clear to me how something could be semi empirical.

    Re: with good accuracy.

    I'm OK with "good accuracy."

    As for "semi-empirical," it sounds to me like they had a formula, but found it collided with reality so they fixed it a bit with real world data.
