Modelling transport processes in heat, mass and fluid flow are always at the focus of the science in the modern era of rapid technological development. This is the second part of the collection of articles. The first part consisting of 14 articles was already published in No. 1A, 2017 and immediately attracted the attention of the scientific society. Now, we will try to present briefly the main results of the articles forming the second part. Fractional calculus is a hot topic in modern modelling studies via accounts of relaxation problems adequately modelled by fractional operators. Alkahtani and Atangana (in this issue, p. 767) present an exact solution of these problems using the Green function method with some integral transform operators. The singular kernel used in this paper is based upon the power law function, which is used to construct the well-known Riemann-Liouville derivative with fractional order.
