Flux Fluid Flow

About

Build it. Watch the physics solve. Understand your system. Flux Flow turns your iPad into a fluid-systems engineering bench. Draw a piping system on the canvas — reservoirs, pumps, valves, tanks, compressors, heat exchangers, orifices, reducers, filters — and the solver runs live as you build. No run button, no waiting: every edit updates pressures, flows, velocities and temperatures across the whole network. Real engineering physics, not a toy • Friction from Colebrook–White with published pipe catalogs and schedules • Fitting losses from the industry-standard Crane K-factor method, size-correct • Compressible gas flow with sonic choking, plus real-gas throttling (Joule–Thomson cooling on letdown) • Water-hammer transients by the Method of Characteristics: valve strokes, pump trips and restarts, boundary-pressure steps, demand changes • Heat exchangers rated from real hardware: shell & tube (Bell–Delaware shell side), plate & frame, and air-cooled fin-fan units — configure fans, CFM, fin geometry and tube bundles • Couple two loops through one exchanger and watch the heat visibly move from the hot stream to the cooling water • Closed loops solve to true equilibrium; ambient zones give every component its local environment — a compressor in a hot room ingests hot air See everything, in your units Imperial or SI throughout. Stack any readouts on any node — pressure, stagnation, temperature, velocity, flow. Tap any point for the static/velocity/stagnation breakdown, and any component for where its pressure went: converted to velocity, spent climbing, or lost to friction. Instrument and automate Place sensors with alarm thresholds, build "when this, do that" automations, schedule timed events, and export PDF reports. Start from solved templates — pump loop, chilled water, compressed air, steam line, CPU liquid cooling — or from a blank canvas. Everything runs on your device.
