About us
Who we are
FluidMechanica is a specialist team for hydraulic and CFD studies of water and wastewater systems. We combine hands-on experience on large EPC and utility schemes with advanced numerical modelling and data-driven methods. FluidMechanica is the CFD and hydraulics division of Pulse Engineering.
Every assignment is built around your question. We give clear engineering recommendations, with plots and model files your team can reuse.

What we do
Services provided
Specialist analyses for tanks, pump intakes, transmission mains, drainage networks and water quality, delivered across the UAE, the wider GCC and internationally.
Surge analysis
Pump trips, valve closure and surge vessel sizing for mains, networks and rising mains.
CFD studies
Tank mixing and water age, pump intakes, manifolds and wastewater structures.
Water network modelling
Pressures, pipe and pump sizing, and valve settings for potable, farm and irrigation networks.
Water quality modelling
Water age, chlorine and chlorine dioxide decay, by-products and dosing strategy.
Drainage & stormwater
Stormwater networks, pump stations and force mains to ADM criteria.
AI optimisation & digital twins
Reinforcement learning controllers that cut pumping energy and excess pressure.

Research
Peer-reviewed AI research
Our deep reinforcement learning method for real-time pump pressure control, trained on an EPANET digital twin of a regional transmission network, is published in the ASCE Journal of Water Resources Planning and Management. In the case study it held every DMA above minimum pressure and cut pumping energy by an estimated 14%.
