Numerical simulations of transport phenomena is one of the valid methods in investigation of crystal silicon growth by CVD for various types of reactors. The present review provides the key summary on the development of fluid dynamic simulations on polysilicon of CVD and hopefully aid in future improvement of this technology. In the solution of CVD reactor models for polysilicon production, the influence of the deposition process on temperature, the transport phenomena and the surface reactions have to be taken into account when discussing the silicon growth rate.

Theme Issue

This theme issue, in two parts, continues research studies of transport phenomena in complex media published in the first part (Alexandrov & Zubarev 2021 Phil. Trans. R. Soc. A 379 , 20200301. ( doi:10.1098/rsta.2020.0301 )). The issue is concerned with theoretical, numerical and experimental investigations of nonlinear transport phenomena in heterogeneous and metastable materials of different nature, including biological systems. The papers are devoted to the new effects arising in such systems (e.g. pattern and microstructure formation in materials, impacts of external processes on their properties and evolution and so on). State-of-the-art methods of numerical simulations, stochastic analysis, nonlinear physics and experimental studies are presented in the collection of issue papers. This article is part of the theme issue ‘Transport phenomena in complex systems (part 2)’.

Internal Transport

Forklift overturning with its operator is the most common and dangerous type of an accident involving internal transport. The forklifts are equipped with safety components to avoid, or reduce the effects of forklift tip-over. However, there is very few information on the effectiveness of such systems. The aim of the research was to evaluate their effectiveness with the use of numerical simulation. The study relied on carrying out numerical simulations of forklift overturning with its operator. Active human body model was used in the research. Human body output parameters, e.g. forces and accelerations of the head and neck were used to estimate injuries sustained by an operator. The effectiveness of the safety components was assessed on the basis of estimated injuries.
