8 Use of the QW-BHM with load rotation

This example is available in .../QW-3D/BHM/Rotation/heat_rota1.QWPro in the QW-Modeller examples directory and can be loaded using File®Open Examples... command from main menu.

General Description

Microwave domestic oven with vertical feed, rectangular shelf, and rectangular food presenting the BHM regime with load rotation.

Geometry

The oven's inside dimensions are 205 mm, 238 mm, and 228 mm in X, Y, Z directions respectively. Its vertical feeding waveguide dimensions are 12 mm, 70 mm, and 48 mm in X, Y, Z directions respectively. The rectangular shelf dimensions are 178 mm, 214 mm, and 4 mm in X, Y, Z directions respectively. The food dimensions are 101 mm, 120 mm, and 24 mm in X, Y, Z directions respectively. The rotation axis is located at X=-101.5mm and Y=-2mm coordinates.

Temperature Distribution

Initial temperature pattern across the load (in -5÷0°C scale) before BHM steps.

Temperature pattern across the load (in -5÷0°C scale) in consecutive 12 BHM steps.
