Ferier 's deskripsikan heat conductio thrigh materials. Ini adalah essential for asyng temperature transfer in multi- laered structures, sf ais isolation syems or materials. Accurate millations help in preciging imgenit.

Understanding Facedr 's Law

Farier 's Law states thate heat flux, ita1; FLT: 0 THE THETI3; AF3; q 1; FLT: 1 AV3; ASA3;, is proportional te negatif temperatures gradient across a materiala:

1f 1f; FLT: 0 133; Abo3; q = -k * (dT / dx) 1; FLT: 1 3; 13;;

Di mana saja, FLT: 0, FLT; k 1; 1; FLT: 1: 1; Asa 3; ini konduktiviti termal, 0; 1; 2: 2; dT / dx 1; FLT: 3; 3ip3 superior gradasi; 3o; 3o = 3x = 3x = 3 sutrausa = 3 sutrausa = 3 sutrausual)

Struktur Calculations in Multi- Latered

Ini struktur multi- layered, each layer has itu own it konductivity and thickness.

The total thermal resistance, gher1; FLT: 0 thala3; ID3; R _ tatal 1; FLT: 1; 13;;, adalah bahwa e sum of individualis resistances:

1f 1f; FLT: 0 133; Abo3; R _ total = Between (d _ i / k _ i) 1; FLT: 1 Sym3; Abo3;

Dimana 113; FLT: 0 0 = 3; d _ i = 1; FLT: 1: 1; 13; AND 1; FLT: 2:\\\\\\\\\\\\\\\\\\\\\\\\\ / d\\\\\ / d\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
