Calorimetry has shown real potential at bench-scale for chem. and biochem. processes. The aim of this work was therefore to scale-up the system by adaptation of a std. com. available 300-L pilot-scale bioreactor. To achieve this, all heat flows entering or ...
Described is a method of manufacturing a module with long-term stability even though it contains a non-heat-resistant material, in particular a photosensitizer. Two glass plates (1, 2) are connected to each other round their edges with an edge-sealing stru ...
Xu et al. have recently published a set of results for boiling heat transfer measurements in a multi- channel micro- scale evaporator for flow boiling of acetone in triangular cross- section channels ( hydraulic diameter of 155.4 mm). In the present collab ...
This paper discusses the effect of diameter on both flow boiling heat transfer and transition from macro to microchannel evaporation. A recently proposed three-zone flow boiling model based on evaporation of elongated bubbles in microchannels is briefly de ...
This thesis presents a system approach with the aim to develop improved concepts for small capacity, high temperature lift air-water heat pumps. These are intended to replace fuel fired heating systems in the residential sector, which leads to a major redu ...
The tubes in shell-and-tube condensers, widely used in refrigeration and chemical process industries, are subjected to condensate inundation from the neighboring tubes. The aim of the present investigation is to study the effect of condensate inundation on ...
A review; microstructured reactors are mainly characterized by their very-high surface to vol. ratio compared to traditional chem. reactors. Multichannel microreactors having channel diams. in the order of ten to several hundred micrometers have sp. surfac ...
A heat transfer assembly for transferring heat from a heat generating device (5) to a circulating fluid, said heat transfer assembly comprising - an evaporator device (3) having at least one microchannel (1) formed therein, in thermally conductive contact ...
Single pan thermal analyses (SPTA) have been performed on Cu–14.5 wt.% Sn, Cu–21.3 wt.% Sn and Cu–26.8 wt.% Sn peritectic alloys. For this purpose, a SPTA assembly has been built and calibrated. As the latent heat is a function of temperature and compositi ...
