Read MoreAdvantages of Corrugated Tubes
Introduction A large number of industries use processes in which heat is transferred between different fluids (or gases). The basic principle of heat transfer is extremely simple: two fluids at different temperatures are placed in …
Read MoreAseptic Filling Fundamentals
General One of the things needed to produce a pasteurised product with a long life which can be distributed at ambient temperature is aseptic packaging. This technology differs from conventional canning techniques in that the …
Read MoreComparison of Laminar and Turbulent Flow
Heat Transfer Flow Regimes One of the important factors controlling heat transfer is the resistance to heat flow through the various “layers” that form the barrier between the two fluids. The driving force for heat transfer …
Read MoreFouling Factors in Heat Exchangers
The fouling factors to be used in the design of heat exchangers are normally specified by the client based on their experience of running the plant or process. If uncontrolled, levels of fouling can negate …
Read MoreHeat Transfer Fundamentals
Introduction As noted here, the basic principle of heat transfer is extremely simple, two fluids at different temperatures are placed in contact with a conductive barrier (the tube wall) and heat is transferred from the …
