Current status

I am now an associate professor at the Geophysical Institute and the bergen Offshore wind centre (BOW) at the University of Bergen (UiB).

Interests

Boundary layer meteorology:

- Characterization of the coherence of turbulence above the sea and in Norwegian fjords.
- Influence of the topography on the mean and turbulent flow characteristics.
- Synthetic turbulence generation in the atmospheric surface layer.
- Influence of the blocking by the surface on the spectral characteristics of turbulence.

Wind engineering:

- Turbulent wind load modelling on long-span bridges.
- Data-driven modelling for structural dynamics.
- Full-scale vibration analysis.

Lidar remote sensing of wind:

- Can scanning Doppler wind lidars measure turbulence?.
- Study of the flow around bridges with short-range and long-range wind lidar instruments.

E. Cheynet's Projects

aerodyn_energi321

Tutorial for the aerodyn software for teaching in ENERGI210

afdd

Automated Modal parameters identification from ambient vibrations measurement using the FDD

ahp_windresources

Multicriteria decision analysis for wind resource assessment and environmental impact

ann_profileatm

Code to get information on the vertical profile of the along-wind standard deviation in the atmospheric boundary layer with a shallow neural network

asd

Converting acceleration to displacements records

atmturbulence_energi322

Set of python functions for the course on random process and atmospheric turbulence in ENERGI322 (UiB)

autostereogram

Demo code for generating autostereograms (aka "Magic Eye" illusions). Includes code to generate the base image, map arbitrary depth mappings, and one hand-generated depth mapping to demonstrate.

bemtfunc

Blade Element Momentum Theory Function for MATLAB

carboncycle7boxes

A seven-box carbon cycle model is implemented in Matlab to simulate atmospheric CO2 concentration from 1750 onwards.

chougulemodel2018

Numerical implementation of the uniform shear model including stability by Chougule et al. (2018)

condwindsim

Matlab code for conditional wind simulation in a 2D plane

dynaresp_beam_td

The dynamic displacement response of a line-like structure to an uncorrelated Gaussian white noise input is computed in the time domain.

dynarespfd

The dynamic response of a suspension bridge to wind turbulence is computed in the frequency domain.

dynaresptd

The coupled dynamic response of a suspension bridge to wind turbulence is computed in the time domain

earthquakesim

Ground acceleration records are simulated using the non-stationnary Kanai–Tajimi model

eigenbeam

Computation of the eigenfrequencies and mode shapes of a simple beam

eigenbridge

Eigenfrequencies and mode shapes of a suspension bridge are computed using a continuum model

The vertical eigenfrequencies and mode shapes of a single-span suspension bridge are computed using the method by Luco et Turmo [1]. For the sake of completeness, the computed modal parameters are compared with those obtained using the method by Sigbjørnsson & Hjorth-Hansen [2] and Strømmen [3].
