Computational Fluid Dynamics Study of the Effects of Drill Cuttings on the Open Channel Flow
(Peer reviewed; Journal article, 2019)A three-dimensional computational fluid dynamics (CFD) study was carried out for drilling fluid flow with drill cuttings in open channels. The flow is similar to the return flow when drilling, stream containing drilling ... -
Constrained numerical optimization of PCR/PLSR predictors
(Journal article; Peer reviewed, 2003)Assuming a fully known latent variables (LV) model, the optimal multivariate calibration predictor is found from Kalman filtering theory. From this follows the best possible column space for a loading weight matrix Wopt. ... -
Contact Resistance and Temperature Rise of Cable Connections in Cable Distribution Cabinets
(Conference lecture, 2020)Initiated by a number of fire accidents in the low voltage switchgear in cable distribution cabinets, investigations have been performed to identify the cause of these fires. The results indicate that the cable connection ... -
Control of a Buoyancy-Based Pilot Underwater Lifting Body
(Journal article, 2010)This paper is about position control of a speci c small-scale pilot underwater lifting body where the lifting force stems from buoyancy adjusted with an air pocket in the lifting body. A mathematical model is developed to ... -
Control of temperature and energy consumption in buildings - a review.
