The importance of being able to construct visualisation artefacts that accurately represent the properties of relevant transport vectors is discussed and appropriate methods based on vector and scalar potentials are described. Attention then turns to heatlines which are becoming increasingly popular for visualising heat transfer process but suffer from ambiguities that arise from the choice of conditions for reference enthalpy. Fortunately, although the assumed reference conditions influence the heatline patterns within the flow, the overall heat transfer analysis provided by the lines may not be adversely affected. The possibility of extending the heatline approach to entropy lines is then considered for two and three dimensional heat transfer fields. The entropy transport vector is not divergence free and a new method that involves a combination of scalar and vector potentials is proposed to correctly construct the lines of the entropy transport vector.14 pagesPDFenUniversity of PretoriaHeat transferThermodynamicsFluid MechanicsVisualization strategiesComputational thermo fluid dynamicsVisualising dataVisualizing dataVisualisation strategiesTransport vectorsVector potentialsScalar potentialsHeatlinesEntropy lines2D3DTwo dimensionalThree dimensionalHeat transfer fieldsDivergenceEntropy transport vectorPresentation
