Abstract
Purpose
The purpose of this paper is to present applications of the topological optimization method dealing with fluid dynamic problems in two- and three dimensions. The main goal is to develop a tool package able to optimize topology in realistic devices (e.g. inlet manifolds) considering the non-linear terms on Navier–Stokes equations.
Design/methodology/approach
Using an in-house Fortran code, a Galerkin stabilized finite element is implemented method to solve the three equation systems necessary for the topological optimization method: the direct problem, adjoint problem and topological derivative. The authors address the non-linearity in the equations using an iterative method. Different techniques to create holes into a two-dimensional discrete domain are analyzed.
Findings
One technique to create holes produces more accurate and robust results. The authors present several examples of applications in two- and three-dimensional components, which highlight the potential of this method in the optimization of fluid components.
Research limitations/implications
The authors contribute to the methodology and design in engineering.
Practical implications
Engineering fluid flow systems are used in many different industrial applications, e.g. oil flow in pipes; air flow around an airplane wing; sailing submarines; blood flow in synthetic arteries; and thermal and fissure spreading problems. The aim of this work is to create an effective design tool for obtaining efficient engineering structures and devices.
Originality/value
The authors contribute by creating an application of the method to design a tridimensional realistic device, which can be essayed experimentally. Particularly, the authors apply the design tool to an inlet manifold.

Abstract
This chapter discusses the main research interests and outputs in the various branches of geography that have influenced the study of tourism from a geographical perspective. It argues that the idiographic tradition has been transversal throughout, leading to the growing interest for tourism within the geography academic community in the last 10 years. There is a focus on the birth of specific research groups, mainly related to a constellation of new university curricula on tourism and—with few exceptions of territorial tradition—to an intermittent availability of public research funds. The chapter concludes with a more general picture of the place of tourism within the geography discipline in Italy and of evolving trends in terms of research results, dissemination, and evaluation.

Abstract
Travel and tourism have had a long history in the Nordic countries, but research on tourism has a relatively short tradition in the region. Recently, academic interest in the Nordic tourism space has grown and diversified especially as a result of increasing numbers of academics and institutions involved with tourism geographies and studies and education in the region. The Nordic context has provided thematic focus areas for empirical studies that characterize tourism geographies in the region, with topics including nature-based tourism, utilization of wilderness areas, second-home and rural developments, impacts in peripheries, and tourism as a tool for regional development. In addition, there are emerging research themes outside of the traditional core topics, such as urban, events, and heritage tourism.

Abstract
This chapter aims to familiarize the reader with some of the important aspects of tourism geography in the German-speaking countries. It starts with a primarily historical-genetic perspective on tourism development and the theoretical traditions associated with them. The second section describes the structure of the discipline, with a focus on the institutionalization of the field in the universities including their research specialization. The chapter maintains that tourism geography plays a marginal role compared with other subdisciplines of geography, though this is reflected primarily in its institutionalization and less so in the research undertaken. The last section deals with the current challenges and future prospects in German-speaking geographies of tourism from a problem-centered perspective.

Abstract
This chapter reflects upon the trajectory of research in the geography of tourism in Spain. It begins with a review, including the evolution of the main topics present in the subdiscipline, with a special focus on developments since the 1990s. This is followed by an analysis of the current role and potential impact of academic tourism geography and a discussion on the recent growth in the publication of research results in international journals. Of importance are the institutional factors that explain the increasing recognition of research on the geography of tourism in Spain. Finally, the chapter discusses the hegemony of positivist approaches pivoting on land use, local and regional development, impact analysis, and landscape transformation, as well as the emerging links between Spanish tourism geography and the international mainstream schools of thought.

Abstract
Depending on the research approach one uses, the development of particular bodies of knowledge over time is the result of a combination of agency, chance, opportunity, patronage, power, or structure. This particular account of the development of geographies of tourism stresses its place as understood within the context of different approaches, different research behaviors and foci, and its location within the wider research community and society. The chapter charts the development of different epistemological, methodological, and theoretical traditions over time, their rise and fall, and, in some cases, rediscovery. The chapter concludes that the marketization of academic production will have an increasingly important influence on the nature and direction of tourism geographies.

Abstract
This chapter demonstrates that despite an unfavorable disciplinary climate for new academic subjects in France, tourism found its place in the French geographical scene almost 40 years ago. The first part traces the history of tourism in French geography until the epistemological turn due to the research laboratory MIT in the mid-1990s. It also focuses on the absence of knowledge of the Anglo-American literature and of multidisciplinarity in French research on tourism. The second part focuses on the valorization of tourism geography research in France, emphasizing the development of multidisciplinarity since the early 2000s, including the creation of a multi-disciplinary tourism laboratory and two journals. The chapter concludes reflecting on the possibility of a science of tourism.
