What is the thermal conductivity of nanofluids?

What is the thermal conductivity of nanofluids?

Thermal conductivity values recorded were very high, with a thermal conductivity of 1.44 W / m k for Ag2Al–water nanofluid at nanoparticle volume concentration, and a thermal conductivity of 1.35 W / m k for Al2Cu nanofluid at the same nanoparticle volume concentration.

How do you find the thermal conductivity of nanofluids?

The most common techniques for the measurement of effective thermal conductivity of nanofluids are the transient hot-wire method [3], steady-state method [4], cylindrical cell method [5], temperature oscillation method [6], and 3-omega method [7] to name a few.

What are the units of thermal conductivity K?

The thermal conductivity, K, of a substance is the quantity of heat in calories, or joules, per second passing through a body 1-cm thick with a cross-section of 1 cm2 when the temperature difference is 1° C. The units are cal/sec/cm2/(° C/cm).

What is the thermal conductivity of water?

0.598 W/m·K
According to literature1 the thermal conductivity of water is 0.598 W/m·K at 20 °C.

Why do we use Nanofluids?

Nanofluids are engineered suspensions of nanometer-sized solid particles in a base fluid. Suspending small solid particles in the energy transmission fluids can improve their thermal conductivity and provides an effective and innovative way to enhance their heat transfer characteristics significantly.
