Analysis of design and performance of polymer and steel plate heat exchanger for OTEC

The global climate agreement signed in Paris in 2015 sets the goal of limiting global warming, which is essential of saving the planet for future generations. The energy transition from a fossil-fuel living to a sustainable society depends on the technological development of using the renewable energy sources on earth. Wind and solar are common...

An investigation into the possibilities concerning Solid Oxide Fuel Cells in naval vessels

The Royal Netherlands Navy (RNLN) seeks to eliminate net green house gasses and other harmful- emissions. In this search, the operability of her vessels need to be secured. One of the options for eliminating net carbon emissions is Power to Liquid (PtL) conversion to Methanol. Fuel cells, and in particular Solid Oxide Fuel Cells (SOFCs) may be...

Absorption of ammonia in an ammonia - ionic liquid solution: A detailed experimental and numerical study of the absorption process

Excessive consumption of non - renewable resources in the recent times has negative effects on the environment, one of the important of which include global warming. This suggests an urgent need for adaption to the sustainable use of the resources, for which the thermal technologies show a lot of scope. Absorption heat pump is a type of heat...

Flow visualization of downward condensing ammonia in a gasketed plate heat exchanger

Ocean Thermal Energy Conversion (OTEC) uses the temperature difference between the surface and deep layers to generate electricity. The temperatures in the ocean hardly vary between day and night or between the seasons, which ensures a very constant energy production with OTEC. In order for OTEC to compete with the current forms of energy...

Practical review & application of CFD to condensing multiphase flows in geometries relevant to Plate Heat Exchangers

In the quest for renewable energy for tropical islands, Ocean Thermal Energy Conversion (OTEC) has revealed itself as one of the most promising technologies. OTEC stands or falls with the performance of the condenser. Plate Heat Exchangers (PHEs) have proven their selves as effective heat transfer<br/>equipment for low enthalpy cycles such as...
