This is the schedule for the oral exam friday June 10th in NHA1120. Best of luck with the exam! 

10.00 Vetle
10.40 Vebj?rn
11.20 Michal
12.30 Boxue 
13.10 Vira
 

This weeks lecture is moved to friday

Since the last part of the excursuses will be presented in class next week, there will be no exercise class Thursday May 12th.

The will be a summary lecture May 13 and May 20 Vira and Boxue will present two different ways to describe water entry through surfaces. For the lecture on May 20, everyone should have read the article by Duez et al. Please let us know if you have any difficulty with accessing the article. 

There will be no lecture this Thursday so that you can work on your mandatory assignment.

Also, after we finish the phase field module we will have two lectures on "water impact of solid spheres" by Vira and Boxue. Everyone should read this article before the lectures.

Here is mandatory assignment 3. A numerical solver that can be used for the final exercise is found here. The deadline is 12th of May.

For additional reading material: the original paper by Cahn and Hilliard (1958) is located here and you can also check out this review paper on the phase-field method.

Todays lecture substituted with the talk by Anne Juel at 12.15 in the same room

of a thin film coating a wire. Here is the original paper by Goren (1962).

Here is mandatory assignment 2. The delivery date is set to Wednesday 13th of April at 1430. In the assignment you are to compare two data sets with your theoretical predictions. The two sets are for droplets of two different viscosities and they are found here: mu=50cSt and mu=100cSt. 

Do Q2-3 here. We will discuss them next Thursday.

See article about 2D similarity solutions for thin film rupture here. What we discussed today can be found in Leal's book, section 6D.

Read this for more information about similarity solutions for the gravity driven thin film equation.

The relevant reading material from Leal's book is section 6A-D.

Please do Q2 here and Q1-2 here. We will discuss them next Thursday (10th).

I have received some questions regarding the derivation of the Rayleigh-Plesset equation using the principle of energy conservation. Here are the definition of the relevant energies. 

Here is the original article by Minneart.

This can be helpful if you are not sure about the expression of viscous dissipation per unit volume.

Here is mandatory assignment 1. The delivery date is Thursday 3rd of march. We will discuss how to organise the experimental part on Friday.

There are no exercises for this week. Instead you should read section 4G 1-2 in Leal's book. For additional material you can check out this review paper on bubble dynamics.

We meet on Friday for our usual lecture.

Her er artikkelen til Proudman og Pearson som vi pratet om i timen.

Please finish Q5-Q7 found here. We will discuss it next Thursday (10th Feb).

Please finish Q1-Q4 found here. We will discuss it next Thursday (3rd Feb).

The first section of the course is discussed in chapter 7A-H in Leal's Advanced Transport Phenomena.

Problems 2-2, 2-4 and 2-8 on pages 99-100 inn Leal's book. We will discuss them next Thursday.

The syllabus for the spring will be selected from these books:

Primarily follow the book by:

¡°Advanced Transport Phenomena¡±, Gary Leal, Cambridge U. P.

¡°Capillarity and wetting phenomena¡±, de Gennes et al., Springer.

As mentioned, you should be able to access the book from Leal using your uio account here:
