Composition Estimation in Dividing-Wall Columns Using Temperature Measurements
(Conference object; Lecture, 2011)
In this work, we propose a method to estimate the product compositions in a distillation column section based on a combination of a number of temperature measurements from different locations in ...
A Wall-Function Approach for Direct Precipitation/Crystallization Fouling in CFD Modelling
(Conference object; Lecture; Peer reviewed, 2015)
The main objective of this paper is to present a generic modelling framework, for the diffusive mass transport through the turbulent, reactive boundary layer of multi-component fluid mixtures that ...
Implementation, Demonstration and Validation of a User-Defined Wall Function for Direct Precipitation Fouling in Ansys Fluent
(Conference object; Lecture, 2017)
In a previous paper (Johnsen et al., 2015) and presentation (Johnsen et al., 2016), we developed and demonstrated a generic modelling framework for the modelling of direct precipitation fouling from multi-component fluid ...
Patient Specific Numerical Simulation of Flow in the Human Upper Airways for Assessing the Effect of Nasal Surgery
The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative ...
Control Structure Design for Optimal Oparation of 4-Product Thermally Coupled Columns
Control and operation of energy efficient complex distillation arrangements like Kaibel and Petlyuk columns can be challenging. This paper discusses the control structure design for stabilizing ...
Marvina – A Norwegian Speech Centric, Multimodal Visitors’ Guide
This paper describes the development and testing of a multimodal visitors’ guide service for guests to the city and university in Trondheim. The system is under continuous development. At the present ...
Probabilistic inference in psychosis and autism
Propagation of anthropogenic noise in the ocean
(Conference object; Lecture, 2012)
Acoustic modeling technique is used to study long range propagation of airgun signals with emphasis on the low frequencies having impact on fish species of commercial interest, the frequency range from 25 Hz to 300 Hz. The ...
Zero Failure Management at Maximum Productivity in Safety Critical Control Room
Predicted growth in air traffic and demand for increased safety, predictability, and efficiency impose additional demands on Air Traffic Management (ATM) systems. Different technologies are currently under development to ...
