Analysis of the thermal conductivity of fluids

Introduction

The thermal conductivity of fluids is a critical parameter in heat transfer applications. It determines the performance of cooling circuits, heat transfer fluids, and cosmic or nutraceutical formulations. Accurate measurement is essential for selecting the right fluids or validating the conformity of new products.

Objective of the analysis

This test aims to measure a fluid's ability to conduct heat. It is necessary for:

• To classify a heat transfer fluid or a coolant
• Compare formulations or batches
• Anticipating thermal performance under usage conditions
• Detect variations in composition impacting conductivity

Analytical techniques used

• Transient Hot Wire Method
• Hot Disk Method
• Liquid thermal conductivity meter

These techniques allow for rapid, accurate measurement over a wide temperature range.

Matrices involved

• Heat transfer fluids (silicone oils, glycol, glycol water)
• Aqueous or saline solutions
• Cosmetic or pharmaceutical liquids
• Cleaning products, technical formulations
• Liquid suspensions or dispersions

Industrial applications

• Thermoregulation (HVAC, electronics, batteries)
• Cosmetics: compliance of thermoactive products
• Food and beverage industry: optimizing the thermal stability of fortified drinks
• Industrial formulation: validation of technical specifications
