CFD Simulations of Pressure Drop in KATAPAK-S Structured Packing
KATAPAK-S is a type of structured catalytic packing, which is used in reactive distillation processes. The dry pressure drop characteristic (the pressure drop in the absence of liquid flow) is of significant importance for the investigation of process hydrodynamics. In this paper, the dry pressure drop within the catalyst packed channels of KATAPAK-S has been investigated using Computational Fl...
متن کاملOptimal-power Configurations for Hover Solutions in Mono-spinners
Rotary-wing flying machines draw attention within the UAV community for their in-place hovering capability, and recently, holonomic motion over fixed-wings. However, they still fall behind in terms of the flight time, power consumption, and safety for centrally-powered and redundant multi-copters have been suggested and studied. In this paper, we investigate about the power-optimality in a mono...
متن کاملA Coupled Unstructured-Adaptive Cartesian CFD Approach for Hover Prediction
An innovative computational fluid dynamics (CFD) approach is employed to predict the aerodynamic performance of hovering rotors. Two different CFD solvers are applied in different parts of the computational domain: a body-fitted unstructured solver near the blade surface to capture complex geometry and viscous effects, and a high-order block-structured Cartesian solver away from the blade to ca...
متن کاملCfd Simulations Comparing Hard Floor and Raised Floor Configurations in an Air Cooled Data Center
An increasing number of companies and organisations have started to outsource their data storage. Although the potential of future investments in data centers is prosperous, sustainability is an increasingly important factor. It is important to make sure that the server racks in data centers are sufficiently cooled whereas too much forced cooling leads to economical losses and a waste of energy...
متن کاملHelicopter Rotor Airloads Prediction Using CFD and Flight Test Measurement in Hover Flight
An implicit unsteady upwind solver including a mesh motion approach was applied to simulate a helicopter including body, main rotor and tail rotor in hover flight. The discretization was based on a second order finite volume approach with fluxes given by the Roeand#39;s scheme. Discretization of Geometric Conservation Laws (GCL) was devised in such a way that the three-dimensional flows on arbi...
