TRI-NODE ENERGY BLENDER (v1.0)
Core principle (works for both electricity and water)
-
Use three identical sources spaced 120° apart on a circle of radius R.
-
Each source sends its energy inward along a radial path to a central heart.
-
The heart is an absorber + blender that prevents head-on collisions and produces one steady output.
-
You do not create extra energy—you combine the three flows into a stronger, smoother, more usable stream.
Geometry rule:
-
Place sources at polar angles 0°, 120°, 240° (or 60°, 180°, 300°).
-
Keep path lengths to the center equal to maintain symmetry and balance.
PART A — ELECTRIC TRI-NODE (three wind turbines → one clean AC output)
Goal
Blend mechanical/electrical power from 3 wind turbines into one stable AC output without the turbines “fighting” each other.
Architecture (block list)
-
3× wind turbines (each with its own generator).
-
3× full-bridge rectifiers (or active rectifiers).
-
1× common DC bus with capacitor bank and a series inductor (LC).
-
1× inverter (grid-tie or standalone AC).
-
Optional: flywheel or supercapacitors at the DC bus.
-
Protection per input: fuse/breaker + reverse-polarity diode.
Why this blends (simple)
-
Rectifiers stop backflow between turbines.
-
Capacitors/inductor act like a soft pillow, absorbing pulsations and phase differences.
-
The inverter drinks from a calm DC lake and outputs one clean AC wave.
Wiring sketch (text)
-
Turbine A → Rectifier A → DC bus (+/−)
-
Turbine B → Rectifier B → DC bus (+/−)
-
Turbine C → Rectifier C → DC bus (+/−)
-
DC bus → Inverter → Load/Grid
Design rules (plain math)
-
Total power:
P_total ≈ P1 + P2 + P3 − losses -
Bus current (choose your bus voltage):
I_bus ≈ P_total / V_bus -
Capacitor sizing for ripple ΔV at ripple frequency f_ripple:
C ≈ I_bus / (2 · f_ripple · ΔV)
Notes: for a 3-phase rectifier, f_ripple ≈ 6 × electrical frequency. With variable wind speed, size for worst-case low frequency and largest I_bus. -
LC filter cutoff:
f_c = 1 / (2π√(L·C)) → pick f_c well below f_ripple. -
Sharing (simple droop control idea if using active rectifiers):
(V_ref − V_bus) = k_i · I_i (each turbine naturally contributes more when bus sags).
Quick example (copy/paste friendly)
-
Target: P_total = 3 kW, V_bus = 400 V, allow ΔV = 10 V, worst f_ripple = 300 Hz.
-
I_bus ≈ 3000/400 = 7.5 A.
-
C ≈ 7.5 / (2 · 300 · 10) ≈ 0.00125 F = 1250 µF.
-
Use ≥ 2200–4700 µF at suitable voltage, plus a small series inductor (e.g., 2–10 mH).
-
Add supercaps (e.g., a few farads at safe voltage with a DC/DC) if you want ultra-smoothness.
Physical layout tips
-
Place the three towers on a circle, 120° apart, same hub height.
-
Keep cable lengths from rectifiers to the heart equal (impedance symmetry).
-
Put fuses near each rectifier output.
-
Heat-sink the rectifiers; put the LC and inverter physically close to reduce loop area.
-
Optional “field heart”: instead of rectifying in towers, bring shafts inward to 120° axial-flux rotors around a toroidal stator at the center; rectify at the stator and then to the same DC bus.
Safety & practicality
-
Over-speed protection (pitch/furl) per turbine.
-
Surge protection on the DC bus.
-
Isolation and a proper earthing scheme.
-
Follow local electrical codes for inverter and grid connection.
PART B — WATER TRI-NODE (three pumps → one smooth outlet)
Two heart options. Both require inlets arranged at 120° around the center.
OPTION B1 — Diffuser → Plenum Heart (pressure blending)
Best when you want minimal swirl and a calm, uniform outlet.
Components
-
3× pumps (preferably identical curves).
-
3× diffusers per inlet (gentle cones).
-
3× check valves per inlet (stop back-beat).
-
1× plenum (round chamber) with honeycomb or perforated baffle.
-
1× outlet with optional flow straightener.
How it blends
-
Diffusers convert jet velocity to pressure (less crash).
-
The plenum and honeycomb equalize pressure and smooth turbulence.
-
Flows add: Q_total = Q1 + Q2 + Q3.
Plain rules and numbers
-
Diffuser half-angle: 5°–7° (gentle to avoid separation).
-
Diffuser area ratio (A2/A1): typically 2–4.
-
Diffuser length: L ≈ (D2 − D1) / (2·tan(θ)).
-
Plenum diameter: ~2–3× inlet pipe diameter (or larger for smoother).
-
Honeycomb: cell length/diameter (L/D) ≥ 6 for good straightening.
-
Head/pressure relation: H = P / (ρ·g).
-
Parallel pumps: at a given head, flow rates add; head ≈ single-pump head minus mixing and friction losses.
Layout (text)
-
Pump A → Check valve → Diffuser A → Plenum
-
Pump B → Check valve → Diffuser B → Plenum
-
Pump C → Check valve → Diffuser C → Plenum
-
Plenum → Straightener (optional) → Outlet
Notes
-
Keep inlet pipes equal length/diameter.
-
Provide air-cushion/accumulator on each inlet if pumps are pulsatile.
-
Maintain adequate NPSH to avoid cavitation.
OPTION B2 — Vortex-Bowl Heart (co-rotating blend)
Best when you like cooperative swirl and want a compact heart.
Components
-
3× pumps.
-
3× tangential inlet pipes entering a circular bowl at 120°.
-
1× central standpipe (aka vortex finder) for the outlet.
-
Optional de-swirler vanes downstream if you want straight flow.
How it blends
-
All three inlets inject same-direction swirl; jets never meet head-on.
-
Angular momenta add; the center region becomes a calm core the standpipe draws from.
-
Q_out = Q1 + Q2 + Q3 (minus losses).
Geometry guidelines
-
Bowl diameter Db sized for total flow; start with standpipe diameter Df ≈ 0.35–0.5·Db.
-
Inlet total area ≈ standpipe area (tune in testing).
-
Curved, tangential inlets reduce separation and losses.
-
Add small accumulators on inlets if pumps pulsate.
Layout (text)
-
Pump A → Tangential inlet A → Bowl → Standpipe → Outlet
-
Pump B → Tangential inlet B → Bowl → Standpipe → Outlet
-
Pump C → Tangential inlet C → Bowl → Standpipe → Outlet
Notes
-
If outlet swirl is a problem, add a short de-swirler (fixed straightening vanes).
-
Provide a drain/vent on the bowl top if air ingestion occurs.
WHAT YOU GET (both systems)
-
One stronger stream instead of three small ones (powers/flows add).
-
Much steadier quality (pulses and gusts average out at the heart).
-
Simpler storage and conversion (one place to attach batteries, tanks, turbines).
-
No crash because the heart is an impedance match:
-
Electric: rectifiers + LC + optional flywheel/supercaps.
-
Water: diffusers + plenum/honeycomb OR tangential vortex bowl.
-
QUICK TABLE-TOP DEMOS (blog-friendly)
Electric micro-demo
-
3 small DC motors (as generators)
-
3 bridge rectifiers
-
1 electrolytic capacitor (e.g., 2200–4700 µF, correct voltage)
-
1 LED strip or small DC/AC inverter
Wire: each motor → rectifier → all to same capacitor → LED/inverter. Spin 1, 2, then 3 motors; watch output steadiness and brightness.
Water micro-demo
-
3 aquarium pumps
-
For B1: make mini diffusers from cone straws; Tupperware plenum; perforated inner cup as honeycomb; one outlet hose.
-
For B2: round jar as bowl; three tangential inlets (side ports); central tube up as standpipe.
120° REQUIREMENT (call-out)
-
Both Electric and Water designs assume three sources at 120° around the center.
-
Keep equal path lengths and mirror the geometry to maximize symmetry and blending.
