Thermal Analysis
How heat enters, moves through and leaves an engineering system — from conduction, convection and radiation fundamentals through steady-state and transient response, thermal contact, temperature-dependent properties, thermal stress, distortion, coupled thermal-structural analysis, thermal buckling, conjugate heat transfer and engineering substantiation.
Heat-Transfer Fundamentals
Thermal Analysis FundamentalsHow conduction, convection, radiation and thermal storage combine to determine engineering temperatures.Heat Transfer by ConductionHow thermal conductivity and temperature gradients govern heat flow through solids.Convection & Heat-Transfer CoefficientsHow fluid motion transfers heat at surfaces and why the convection coefficient is a modelling parameter rather than a universal constant.Thermal RadiationHow surfaces exchange thermal energy through radiation and why temperature and emissivity strongly influence the result.
Thermal Response
Steady-State Thermal AnalysisPredicting equilibrium temperatures when heat input and heat rejection no longer change with time.Transient Thermal AnalysisPredicting how temperature evolves through time during heating, cooling and changing operating conditions.Thermal Mass, Heat Capacity & Time ConstantsHow mass and specific heat control the rate at which engineering hardware changes temperature.Thermal Boundary ConditionsHow temperatures, heat fluxes, convection, radiation and contact conditions define the thermal problem.Thermal Contact ResistanceWhy mechanically contacting surfaces can still present significant resistance to heat transfer.Internal Heat Generation & Heat SourcesHow the magnitude, location and timing of internally generated heat influence thermal response.Temperature-Dependent Material PropertiesWhy thermal and structural properties may need to vary with temperature to represent the real system.Thermal Gradients & Through-Thickness EffectsHow non-uniform temperature fields create local heat flow, bending and differential expansion.
Thermal-Structural Behaviour
Thermal Expansion & Thermal StrainHow temperature change produces free thermal strain and why restraint converts that strain into structural load.Thermal Stress AnalysisHow restraints, gradients and material mismatch transform temperature changes into stress.Thermal Distortion & Dimensional StabilityHow temperature affects alignment, geometry and functional performance even when structural strength remains acceptable.Coupled Thermal-Structural AnalysisHow calculated temperature fields are transferred into structural models to predict stress and deformation.Thermal Buckling & Thermally Induced StabilityHow restrained thermal expansion can generate compressive loads and structural instability.
Multi-Physics & Verification
Conjugate Heat Transfer & CFD CouplingHow fluid flow and solid conduction are solved together where convective behaviour cannot be adequately prescribed.Thermal Verification, Sensitivity & Test CorrelationHow energy checks, sensitivity studies and measured temperatures establish confidence in thermal predictions.From Heat Input to Thermal-Structural SubstantiationTurning thermal environments and predicted temperatures into traceable structural or functional engineering evidence.
