Design Of Theoretically Optimal Thermoacoustic Cooling Device

Evaluation of Thermoacoustic Cycles for Cooling Applications

The most promising applications for thermoacoustic cooling are investigated from the perspective of the thermodynamic second law efficiency in this paper. A design optimization program interacting with the thermoacoustic simulation program known as DELTAE was developed. Then it was applied to two of the most common configurations for standing-wave thermoacoustic coolers in order to determine th...

Optimal Shape Design for a Cooling Pin Fin Connection Profil

A shape optimization problem of cooling fins for computer parts and integrated circuits is modeled and solved in this paper. The main purpose is to determine the shape of a two-dimensional pin fin, which leads to the maximum amount of removed heat. To do this, the shape optimization problem is defined as maximizing the norm of the Nusselt number distribution at the boundary of the pin fin's con...

Optimal Design of Cooling Water Systems

Re-circulating cooling water systems are generally used to remove waste heat from hot process streams in conditions above the ambient temperature in many types of industries such as chemical and petrochemical, electric power generating stations, refrigeration and air conditioning plants, pulp and paper mills, and steel mills. Typical re-circulating cooling water systems are constituted by a mec...

Information-Theoretically Optimal Histogram Density Estimation

We regard histogram density estimation as a model selection problem. Our approach is based on the information-theoretic minimum description length (MDL) principle. MDLbased model selection is formalized via the normalized maximum likelihood (NML) distribution, which has several desirable optimality properties. We show how this approach can be applied for learning generic, irregular (variable-wi...
