Human Heart Conjugate Cooling Process: Unsteady Thermo-Fluid-Stress Analysis

The main objective of this work was to demonstrate computationally that realistic human hearts can be cooled much faster by performing conjugate heat transfer consisting of pumping a cold liquid through the cardiac chambers and major veins while keeping the heart submerged in cold gelatine filling a cooling container. The human heart geometry used for simulations was obtained from three-dimensi...

Improving the Cooling Process of Heavy-Duty Engines through Three Dimensional Simulation of Fluid Flow in its Coolant Centrifugal Pump

This paper investigates 3D simulation of fluid flow in a centrifugal pump from the Detroit Diesel company to extract possible engine cooling trends.  The velocity and pressure profile of water, the coolant, is analyzed and the characteristic curves of the pump are derived. This provides a useful evaluation of the pump performance at all working conditions. For this aim, a computational fluid dy...

Process Intensification in Multiphase Reactors

Introduction Applications of multiphase technology are prevalent in petroleum refining, synthesis gas conversion to fuels and chemicals, bulk commodity chemicals, specialty chemicals, conversion of undesired by-products to recyclable products, manufacture of polymers, biotechnology and pollution abatement. In these processes the reactor performance is crucial: it determines the number and size ...

Process intensification in mechanical pulping

Process intensification is a term used in the chemical process industry for major improvements in the process design leading to radical changes in process complexity, equipment size and efficiency. We suggest that a similar approach is applied in the pulp and paper industry. We have focused on the production of mechanical pulp, but a similar approach can be applied to other areas within the pul...
