Item Open Access Computational approach for investigating nanoscale interfacial ice adhesion trends(Royal Society of Chemistry, 2023-12-12) Vincent, Abhay; Pervier, Marie; Pervier, Hugo; Nalianda, DevaiahFor developing high performance, low-energy ice protection systems, it is vital to understand the icing physics at the interface of the ice and substrate. Macroscopic experiments have known limitations when it comes to explaining the adhesion characteristics of ice. There is a need to look at the microscale behaviour of ice and how it interacts with the surface it adheres on. The article describes application of molecular dynamics to the ice-substrate problem by modelling two major modes of ice adhesion test – tensile and shear tests, which are used for ice adhesion strength determination. The coarse-grained model of water is nucleated to form ice at the temperature which is designated for ice adhesion test on a macroscopic level. Steered molecular dynamics (SMD) is then applied to the nucleated ice cube to then obtain tensile and shear adhesion strengths over various FCC surface morphologies that represent the crystal structure of metallic substrates. The results obtained from the adhesion simulations are then used to compare the nanoscale trends on ice adhesion to the macroscale ice adhesion trends. The simulation results show that while contact area and temperature variations have similar trends to the observed macroscopic trends, other variations like tensile and shear loading rate variation at the nanoscale are not directly understood from macroscopic interpretations of ice adhesion.Item Open Access High Speed Camera Tests - ERICE(Cranfield University, 2023-06-06 14:25) Vincent, Abhay; Pervier, Marie; Pervier, HugoThis item contains the data from the High speed camera tests for ERICE project based on conditions 1 and 2 of the test matrix. Data includes: 1) High Speed camera videos for two test conditions (x2) - '.avi' format 2) Labview files (x2) - '.lvm' format (read with MS Excel) 3) README txt file (x1) - explaining the headers for the labview data and the instrumentation involved. Test 1 refers to the 50k RPM condition from the test matrix and Test 2 refers to the 60k RPM condition from the test matrix.Item Open Access Malvern Tests - ERICE(Cranfield University, 2023-06-06 14:25) Vincent, Abhay; Pervier, Marie; Pervier, HugoThis item contains the data from the tests done for characterization of flow using Malvern Particle Analyzer for the ERICE project.

Test 1 refers to the test run at 60k RPM & Test 2 refers to the test run at 50k RPMItem Open Access README [Test Matrix & Description - ERICE](Cranfield University, 2023-06-06 14:25) Vincent, Abhay; Pervier, Marie; Pervier, HugoThe item consists of a presentation ('pptx' format) which describes the two distinct test matrix conditions for the ERICE tests and a text file which describes the process of all the various tests performed within this research work. These conditions were used for all the testing done within the ERICE project.Item Open Access Test Matrix Condition 1 Tests - ERICE(Cranfield University, 2023-06-06 14:26) Vincent, Abhay; Pervier, Marie; Pervier, HugoThis item contains the condition 1 tests conducted under ERICE. These tests were done at 60k RPM of the turbocharger and were only to observe the ice accretion and no scrape tests were performed for tests in these conditions. The item includes the following data: 1) Labview files (x8) - '.lvm' format (read with MS Excel) 2) Video files (x8) - '.mkv' format 3) README txt file (x1) - explaining the headers for the labview data and the instrumentation involved - Test 1 refers to Wearlon sample; Test 2 refers to AA Fsmooth sample; Test 3 refers to Al sample; Test 4 refers to AA F75 sample; Test 5 refers to Thin SAA + TCS sample; Test 6 refers to Thin SAA + PTFE; Test 7 refers to Xylan sample; Test 8 refers to WSAA Fsmooth sampleItem Open Access Test Matrix Condition 2 Tests - ERICE (Scrape Test Data)(Cranfield University, 2023-06-06 14:26) Vincent, Abhay; Pervier, Marie; Pervier, HugoThis item contains the details of the 40 total successful test runs for the Condition 2 of the ERICE test matrix. Ice was accreted using this condition and then tested in the Scrape Test setup to obtain adhesion test values for 8 samples. The item consists of the following data types: 1) Labview files for rig sensors (x39) - ".lvm" format - to be read using Excel, 4th test for Xylan had no file due to recording error 2) Labview files for scrapetest (x41) -.lvm format" - to be read using MS Excel 4th test for Xylan had no file due to recording error extra test for AA Fsmooth 5th test 3) Video files (x39) - ".mkv" format 4) Color-coded test matrix (x1) - ".xlsx" format - to be read using MS Excel 5) README txt file (x1) - explaining the headers for the labview data and the instrumentation involved. Each sample apart from AA Fsmooth has 5 tests completed and are labelled in that order. AA Fsmooth has an extra test and hence the scrapetest files are labelled as 5a and 5b."Item Open Access Trace-wire Tests - ERICE(Cranfield University, 2023-06-06 14:25) Vincent, Abhay; Pervier, Marie; Pervier, HugoThis item contains the data from the trace-wire testing performed for the ERICE project. The following files are present within this item: 1) Labview files (x3) - ".lvm" format (to be read in MS Excel) 2) Video files (x3) - ".mkv" format 3) README txt file (x1) - explaining the headers for the labview data and the instrumentation involved. Test 1 refers to Aluminium sample Test 2 refers to Wearlon sample Test 3 refers to AA Fsmooth sample
