Digital transformation and the new combinations in tourism: a systematic literature review
Publication . Gutierriz, Ives; Ferreira, João J.; Fernandes, Paula Odete
This study aims to analyse the research involving the evolution and development of digital transformation and the new combinations in tourism development. To this end, a systematic literature review was conducted in the Scopus and Web of Science databases, which gathered 167 studies published between 1997 and 2023, representing the final sample analysed in this review. The results allow the identification of three main findings: i) there are four thematic groups - Digital Marketing, Digital Economy, Education and Hospitality and Free Digital; ii) there is a growing interest in the research of this topic and the use of available technologies for the development of tourism companies and their businesses and the respective wider economy; and, iii) digital transformation tends to be a positive factor when applied to the tourism sector. This research further proposes a framework that provides a detailed description of these studies with key issues and contributions from the available literature.
Contributions to accelerating a numerical simulation of free flow parallel to a porous plane

Flow models over flat p orous surfaces have applications in natural processes, such as material, food, chemical processing, or mountain mudflow simulations. The development
of simplified a nalytical or numerical models can predict characteristics such as velocity, pressure, deviation length, and even temperature of such flows for geophysical and engineering purposes. In this context, there is considerable interest in theoretical and experimental models. Mathematical models to represent such phenomena for fluid mechanics have continuously been developed and implemented. Given this, we propose a mathematical and simulation model to describe a free-flowing flow pa rallel toa
porous material and its transition zone. The objective of the application is to analyze the influence o f t he p orous matrix on the flow u nder d ifferent m atrix p roperties. W e i mplement a Computational Fluid Dynamics scheme using the Finite Volume Method to simulate and calculate the numerical solutions for case studies. However, computational applications of this type demand high performance, requiring parallel execution techniques. Due to this, it is necessary to modify the sequential version of the code. So, we propose a methodology describing the steps required to adapt and improve the code. This approach decreases 5.3% the execution time of the sequential version of the code. Next,
we adopt OpenMP for parallel versions and instantiate parallel code flows and executions on multi-core. We get a speedup of 10.4 by using 12 threads. The paper provides simulations that offer the correct understanding, modeling, and construction of abrupt transitions between free flow a nd porous media. The process presented here could expand to the simulations of other porous media problems. Furthermore, customized simulations require little processing time, thanks to parallel processing.
