ABSTRACT
This chapter addresses both the issues and to point to some of the ways forward. It discusses the fundamental scaling laws pertinent to cold regions, and identifies cold regions' problems that should benefit from centrifuge modelling and many areas where fundamental knowledge is lacking. The chapter explores the design of a model and the actual technology that is available. It considers package design and provides some examples of specific tests. The chapter also provides a typical cold regions' test, the required boundary conditions, the degree of heat transfer needed, and the modelling methodology required to implement a test. It explains the models in which frozen material is being tested and in which heat transfer is required during centrifuge flight. The chapter deals with the range of possible cooling systems that can be used with a centrifuge. It analyses the methods for transferring heat energy from a cold/heat source to or from the model itself.
