••
TL;DR: In this paper, a numerical model was developed to predict the flue-ash particle deposition rate by considering particles transport, sticking and rebound behaviors based on the software FLUENT, extended by user-defined functions (UDFs).

••
TL;DR: In this paper, the fluid flow and heat transfer characteristics of finned tube heat exchangers were numerically investigated by examining different oval and circular tubes, and the results revealed that using the oval fin-tube can not only reduce the flow resistance but also improve the heat transfer capacity of the heat exchanger which effectively improved the fin efficiency.

••
TL;DR: In this paper, a new numerical model has been developed to predict the condensation rate of sulfuric acid and condensate acidic solution concentration on heat exchanger surfaces by correlating the vapor-liquid equilibrium (VLE) data of H 2 SO 4 -H 2 O solutions from experiments and in conjunction with multi-component diffusion theory.

TL;DR: Based on the prediction model of acid deposition, a three-dimensional numerical simulation was performed for acid deposition characteristics of H-type finned tube bank with 10 rows, and the effect of six geometric parameters (spanwise tube pitch, longitudinal tube pitch and fin height, fin pitch, fin thickness and slit width) and Reynolds number were examined as discussed by the authors.
