Visualization through IR camera of the self-adaptive flow rate regulation in function of the temperature in an array of microfluidic cells for fixed boundary conditions.

A joint measurement session of the Streams Project took place yesterday, 19^th of June, at the facilities of the Polytechnic School of the University of Lleida. Today, the last General Assembly of the Project is ongoing.

The next General Assembly of the STREAMS Project will be held in the University of Lleida on Thursday 20/06/2019. Among other aspects, the assembly will include an experimental demonstration of work packages 2 and 5.

The previous day, Wednesday 19/05/2019, the partners will meet to perform the final experimental tests together.
