Preliminary Fluid Selection• Dowtherm G

• Temperature Range – 20°F - 675°F• Cost – Unknown (Dr. Kandlikar said less than $5/gal)• Availability – Needs to be ordered (awaiting response from

supplier)• Low viscosity• Low Thermal Conductivity• Non-Toxic

TANK AND COMPONENTS, TUBING & PIPING


Concept Generation & Selection

16

PEW Chart – Tank


17

Preliminary Selections

Tank: Parker SMS30• 30 gallon steel tank• Lowest price, can be bought locally• Easy installation of heat cartridges due to rectangular

shape


18

PEW Chart – Tank Insulation


19


Tank Insulation: High Temperature Fiberglass & rigid foam

• High Temperature Fiberglass close to tank• Temperature Range: 0°F to 450°F• High density

• Add cheap rigid foam to outer layer to help minimize heat loss over time


20

PEW Chart – Mixer


21


Tank Mixer• TBD, depending on tank

Tubing & Piping• Metal rigid piping • Metal braided flexible tubing


22

PUMP SELECTION



23

PEW Chart


24

Preliminary Pump Selection

Gear Pump• Maximum temperature of up to 500°F• Maximum pressures from 250 psi to 500 psi• Maximum flow rates from 20 GPM to 120 GPM• Fluid Compatible• Small footprint – approximately 1 ft3 before motor• Maximum 1800 rpm


25

HEATING COMPONENTS



26

PEW Chart


27

Preliminary Selection

Cartridge Heaters• Using multiple smaller heaters helps increase power

potential and thus decrease time to heat the fluid• Relatively low cost per Watt (~ $0.03/Watt)• Using multiple heaters allows for even distribution of

temperature• Drill holes in sides of tank to attach heaters


28

Power Requirement

Cp Fluid = 1.878 KJ/kg*K

ρ Fluid = 973.25 kg/m3

Volume (30 gal) = .114 m3

ΔTemp = 200°CTime = 1 hr = 3600 s
