In order to improve the climate resilience and liveability of Curaçao’s Inner-City, various
interventions are proposed for Wilhelminaplein in Punda to mitigate the problem of heat stress, along with socioeconomic issues. This is done while keeping the problem of water scarcity in mind. Among various problem locations in the Inner-City, Wilhelminaplein was chosen as a development site because of its high potential and advantageous location. The main problems facing Wilhelminaplein are found to be extreme heat and lack of clear function, shade and maintenance.
Various possible solutions are proposed and discussed with experts, including a landscape architect and urban planner. Following this, the interventions are finalized and presented to various stakeholders, including representatives of relevant government agencies. Through a workshop, the stakeholders provided feedback on their preferred set of interventions.
The proposed interventions are subdivided into ’quick wins’, cool spots and additional interventions.
To quantify the effectiveness of the interventions, PET reductions of the proposed interventions are modelled using the modelling software RayMan. Along with the PET reduction, the initial cost, water usage, required level of maintenance and implementation time frame, are analysed for each proposed intervention.
To facilitate the practical implementation of the proposed interventions, an overview is given of which steps the relevant government agencies still need to take in terms of research, designs, and applying for permits.

Oil-in-water emulsions are very common in industrial processes, and understanding the fac- tors governing emulsification and de-emulsification is crucial. A mechanism through which de-emulsification commonly takes place is coalescence, being the act of two dispersed-phase droplets coming together to create a single larger droplet. Due to density differences, it is common for dispersed phase droplets to form a creaming layer at the top of the emulsion, in- creasing the likelihood of coalescence and therefore de-emulsification. The goal of this thesis is to use the lattice Boltzmann method to simulate the rising of a dispersed phase oil droplet towards a creaming layer due to buoyancy effects and to quantify the effect of the viscosities of both phases on the velocity with which aforementioned droplet rises. This is done using the Shan-Chen psuedopotential method. After introducing gravity into the simulation the the droplet is allowed to reach a terminal velocity vt. This is done for independently varying viscosities for both the dispersed phase and continuous phase (νd and νc respectively). A weakly inverse relation was found between vt and νc. An estimation for the terminal velocity of a droplet rising due to creaming behavior is found by cancelling drag force found from Stokes’ law against the buoyancy force. Found results were not in agreement with said estimation. Different explanations for this discrepancy are varying droplet diameters, varying droplet densities, droplet deformation and high velocity fluctuations. The terminal velocities were also compared to the ratio between the viscosity of both phases, but no correlation was found.
