Dear Experts,

Find the attachment, How will find thermal conductivity of Ternary Hybrid Nanofluid?

If I selected 3 nanoparticles (NP1, NP2 & NP3).

I prepared samples in different volume concentrations like

NANOFLUIDS = 1. NP1+BF, 2. NP2+BF & 3. NP3+BF

HYBRID NANOFLUIDS = 1. NP1+NP2+BF, 2. NP2+NP3+BF & 3. NP1+NP3+BF

TERNARY HYBRID NANOFLUIDS = NP1+NP2+NP3+BF

I have calculated the thermal conductivity of the individual NANOFLUIDS (Knf1 Khf2 Knf3) & HYBRID NANOFLUIDS (Khnf1 Khnf2 Khnf3).

Now, I want to calculate the thermal conductivity of the ternary hybrid nanofluid (Kthnf).

In the formula, only a single value of Khnf is mentioned, but since I have three different values Khnf1 Khnf2 Khnf3.

I am not sure which one should be substituted for Khnf ?. How should I apply these values to correctly determine Kthnf ?.

Kindly suggest your valuable points and also refer previous research article.
