Studying the effect of boundary layer suction: Using design tools based on finite difference and integral methods

With the increasing interest for renewable energy resources in the last couple of decades, the possible benefits of flow control is brought under more and more attention. Boundary layer suction (or blowing) is one type of control that has proven its applicability in various fields. Being able to predict these effects on the boundary layer and...

Atmospheric Carbon Dioxide Reduction: An evaluation and discussion of our options

If one wants to enter a discussion about controversial (environmental) problems like the greenhouse effect with the actual intention of working through to a solution and implementing this solution, there are several steps to be taken. First of all, the nature, size and impact of the problem have to be determined and generally acknowledged....

Sustainability of Palm Oil Production: A Thermodynamical Approach

In the environment report of 1998 [2] Unilever’s Environment Policy is stated: ‘Unilever is committed to meeting the needs of customers and consumers in an environmentally sound and sustainable manner, through conscious improvement in environmental performance in all our activities.” [2]. Environmental problems are part of the trilemma the world...

Pedestrian flow out of buildings

In this report we describe the phenomenon of pedestrian flow in case of large crowds leaving stadiums, buildings etc. First we made an extensive search through literature existing on this subject. We searched for existing models describing the flow of pedestrians under different conditions. Two researchers from the former Sovjet Union developed...
